POOL WATER CARE FOR VINYL LINER POOLS

POOL WATER CARE FOR VINYL LINER POOLS

With proper pool water care, your vinyl liner pool is designed to hold the same water for many years. You filter it, and you treat it over and over again, as part of your pool water care. Over time the water can drift out of balance and cause corrosion, scaling, or staining. Prevent these problems by keeping the water balanced. Use a good quality test kit to measure PH, Alkalinity, Calcium hardness, and chlorine residual.

Also tests might be needed for copper, iron, and chlorine stabilizer, to spot trends that could also cause problems.

PH is a numbered scale from 0 to 14, that measures the acidity(that’s below 7), or alkalinity (that’s above 70, of the water in a vinyl liner pool. Proper PH is 7.2-7.8. Low PH causes corrosion and wrinkles in vinyl liners. High PH causes cloudiness, scale and ineffective chlorine.

Total Alkalinity measure the level of a chemical that stabilizes or anchors the PH. The proper range for TA is 80-120 for vinyl liner pools. Keepin within this range will prevent PH drift and the problems mentioned above. High levels of TA can easily be lowered by adding PH Decreaser or Muriatic Acid.

Calcium measures calcium minerals in your pool water. Levels vary around the country from soft water (50ppm) to hard water(over 300ppm).

For vinyl liner pools the proper range is 125 to 250ppm. Low levels can be bad for vinyl liners and high levels can cause cloudiness and scale.

Copper and iron is a problem in some water. Uncontrolled they can cause staining and discoloration. You must test for these and take the appropriate measures, (adding chemicals), to eliminate copper and iron in a vinyl liner pool.

Chlorine Stabilizer refers to a chemical level that reduces chlorine loss due to UV rays in sunlight by 50% or more. Test the level and add stabilizer as per instructions from the chemical manufacturer. All of the above is important in your pool water care.

POOL BUILDER IN SOUTH JERSEY DISCUSSES CAL HYPO ON VINYL LINER POOLS

POOL BUILDER IN SOUTH JERSEY DISCUSSES CAL HYPO ON VINYL LINER POOLS:

Calcium Hypochlorite, or cal hypo, has been a staple of chlorine water sanitizing for decades and decades. However this South Jersey Pool Builder believes there is too much use of cal hypo for pool water sanitizing. It does provide excellent water clarity while destroying contaminants in pool water, such as those found in sweat, urine, and windblown debris.

You can buy it in slow dissolving tablet forms, or more rapidly dissolving granular forms. When added to a pool, PH, alkalinity and hardness of treated water may drift upward. The relative amounts of effectiveness will depend on the PH of the pool water. So always keep your PH between 7.2 and 7.6

Cal hypo is a strong oxidizer that requires proper attention to the manufacturer’s instructions for application, storage and handling. It can be toxic if mishandled! It can be dangerous as it is very corrosive and if improperly handled or stored improperly it can even explode and cause toxic gases.

Cal hypo comes in varying strengths; 65 percent up to 80 percent. It has been used as a disinfecting agent in swimming pools since 1928.

As the name suggests, calcium hypochlorite contains calcium. When cal hypo is used it is adding calcium hardness to the water each time cal hypo is added. This can eventually bring the calcium hardness level up too high. This would then require means to lower the calcium hardness, such as partially empting and re-filling the pool.

 

When it comes to vinyl liner pools, this South Jersey Pool Builder would much rather use Di-Chlor or lithium to shock and sanitize vinyl liner pools. They mix easier and do much less harm to vinyl liners. They will not bleach the liner as much. But they will do an excellent job of sanitizing the pool water and give good clear water to swim in, if the amount of chlorine is kept between 1 & 3ppm.

WHAT IS A SWIMMING POOL PUMP AND HOW DOES IT WORK?

WHAT IS A SWIMMING POOL PUMP AND HOW DOES IT WORK?

A swimming pool pump is made up of two parts: the motor itself and the front-end of the pump, called the ‘wet-end”, which actually moves the pool water.

The motor spins a shaft and mounted on the end of that shaft is an impeller, which is enclosed in a housing called a volute. As the shaft spins the impeller, water is drawn through the inlet port into the center of the impeller.

From there the pool water is then forced through a series of slotted vanes in the impeller eventually striking a diffuser, which direct the flow through the outlet port.

To keep the electric motor isolated from the flow of the water and to prevent leaks, the entire pump assembly is made watertight by a series of gaskets, O-rings and seals.

A swimming pool pump has a motor that is rated in horsepower, such as 3/4, 1- and 2-horsepower.For years swimming pool builders have thought bigger is better. But that proved to be not true.

Over-sizing the pump is a big problem. First, you can only push so much water through a swimming pool’s plumbing pipes. A great problem is the amount of electricity being consumed by bigger horsepower pumps.

That’s why we’re seeing laws in some states about the size of the swimming pool pump that can be placed in a swimming pool. We now believe that smaller horsepower pool pumps will actually do a better job of moving pool water and better filter the pool water.

VINYL-LINER-POOL TECHNICAL BULLETIN

VINYL-LINER-POOL TECHNICAL BULLETIN:

Don’t underestimate nitrogen in your vinyl-liner-pool water.Let’s say your water is properly balanced and crystal clear but you cannot maintain a free chlorine residual, or algae plagues the water in your vinyl-liner-pool. These problems and others can be the result of nitrate nitrogen build-up in your water, and treating this problem may be a difficult task.

WHAT IS NITRATE NITROGEN?

It’s a compound that forms naturally in our soil and atmosphere. They can also be present in water. They cause problems and you want to get rid of them, but that isn’t easy to do. Nitrate, which consists of a single nitrogen atom connected to three oxygen atoms (NO3), is extremely stable. As a result, it can make its stay in your vinyl-liner-pool water an extended one.

 

HOW DID MY VINYL-LINER-POOL GET IT?

Fertilizer is the moist common source of nitrate intrusion. Many fertilizers contain a high level of nitrate nitrogen. It can leach out of the surrounding soil, be washed into the pool by rain or a sprinkling system. It can fall from trees or plants, etc. In addition overspray form neaby farms, gardens, or lawns can increase nitrate levels in your vinyl-liner-pool water. In fact, many city water sources contains contain a low level of nitrates. The EPA has set the maximum acceptable  nitrate level of 10 ppm in municipal water supplies. Therefore, the nitrate nitrogen may be at problematic levels from the beginning when you fill your pool with fresh water.

NITRATES WILL INCREASE THE SANITIZER (Chlorine) DEMAND IN POOL WATER.

Chlorine demand will be greatly increased. And algae loves nitrates, so algae will grow in the pool water. If your nitrate level is below 10ppm, you should be able to control algae with regular methods. Ideal chlorine levels may be ineffective in preventing algae when high nitrate levels are present. TEST YOUR VINYL-LINER-POOL WATER FOR NITRATE LEVELS.

WHAT’S THE TREATMENT?

Prevention is the best method. Find the source of the nitrates. Take steps to protect your vinyl-liner-pool from being invaded. Cover the pool when fertilizing, shower before entering the pool, keep animals out, remove leaves from the water.

The only way to lower the nitrate level once it is too high, is to partially drain the pool and refill. The nitrate level should not exceed 10ppm.

SALTWATER POOL CHEMISTRY: SORTING FACT FROM FICTION

SALTWATER POOL CHEMISTRY: SORTING FACT FROM FICTION

Understanding saltwater pool chemistry starts with sorting the facts from fiction. Many common misconceptions stem from a lack of knowledge around the chemistry of saltwater pools. The first misunderstanding is that they fundamentally different and don’t use chlorine as a sanitizer. Saltwater pools actually create free chlorine from the electrolysis of dissolved salt in the pool water. They experience many of the same problems as traditional chlorine pools, including problems with water balance, maintaining a chlorine residual, solving cloudy water and battling algae and breaking down combined chlorine.

Water balance is key to maintaining any pool. PH is a key water balance parameter. The process of generating chlorine causes the PH to rise over time. If left unchecked, PH will rise and can lead to multiple problems in the pool water, including ineffective sanitizing, cloudy water, scaling and algae. To combat this trend of rising PH, application of a weekly PH decreaser may be necessary for saltwater pools. Of course to determine this one must test the level of PH in the water, with test strips or a liquid test kit.

Another issue saltwater pools may experience is failure to maintain a free chlorine residual. This may be traced to a the pool experiencing a chlorine demand, or the cell may be no longer physically capable of producing enough free chlorine. The process of chlorine demand, and actually the lack thereof, quickly leads to problems such as cloudy water and algae. The problem may become too great for the chlorine salt cell to overcome. The addition of a full strength chlorine shock product is often needed to restore a sanitizer residual to the saltwater pool.

Don’t forget, over time the salt cell slowly wears out. This may cause it to produce less free chlorine than is needed. Also, not running the cell long enough will cause it to produce too little free chlorine. And an undersized salt cell will also be a cause for too little free chlorine being produced for the size of the pool.

Don’t forget to check the salt-level in the pool. Follow the manufacturer’s instructions for salt levels. Most recommend a range of 2600 to 3500 ppm of salt. Low water temperature will also cause the cell to stop making enough free chlorine. Most salt systems will shut down when temperatures reach below 60 degrees F. A traditional algicide should be used in saltwater pools just as in a typical chlorine pool.

With proper maintenance and a little care, saltwater pools provide a premium experience to pool owners.

VINYL LINER POOLS HAVE DEVELOPED TO THE POINT WHERE THEY BECOME A BACKYARD DESIGN ELEMENT

VINYL LINER POOLS HAVE DEVELOPED TO THE POINT WHERE THEY BECOME A BACKYARD DESIGN ELEMENT:

Vinyl liner pools have become a design element that can harmonize with the entire backyard setting. That has been a trend that homeowners have been pushing for the last 5-10 years. We’re seeing more rock patterns, different types of tile patterns, and now the patterns in liners work visually outside, just the way a tile backsplash works in the kitchen.

Overall, homeowners want the vinyl liner pool to be a part of the entire backyard design and atmosphere, which is why we’re seeing so many new and different types of tile patterns available. And it’s why the vinyl liner pools come in so many different shapes and sizes. Homeowners want their pool to fit in with the rest of their backyard design.

Vinyl liner pools are built now as part of the entire environment, with outdoor kitchens, fire and water features, lounger-ledges and shallow entry areas for toddlers,etc. There’s no question today that a vinyl liner pool can be built the same way you would a concrete pool in terms of design flexibility, but in a shorter construction time-frame, and a lower cost than concrete pool construction.

But one can still get a standardized vinyl-liner pool design, that will work well in many backyards at a lower cost. Not everyone wants to spend $60,000 to $100,000 on their pool and backyard. Vinyl liner pools are great for this, because they can compete with concrete pools for a custom design and price, as well as a great pool of a standard design, for a lower budget.

VINYL LINER POOL BUILDERS DISCUSS COST DEFFERENCE BETWEEN VINYL POOLS AND CONCRETE POOLS

VINYL LINER POOL BUILDERS DISCUSS COST DIFFERENCE BETWEEN VINYL POOLS AND CONCRETE POOLS

Vinyl liner pools have evolved dramatically in recent years and now offer a list of benefits that compare favorably to concrete or gunite pools, and at reduced costs both in new installation and ongoing maintenance.

A number of vinyl liner pool builders were recently asked key questions about those developments and how they think this preferred method of construction stacks up today.

WHAT ARE THE COST DIFFERENCES BETWEEN VINYL POOLS AND CONCRETE POOLS?

All things being equal, in building a vinyl pool versus a comparable concrete pool, the concrete pool is going to cost about 60 percent more. In other words a $60,000 pool in vinyl, will be $100,000 in concrete. A vinyl liner pool is about two-thirds the cost of an equivalent concrete pool. And a large part of what makes that cost difference is the concrete or gunite.

There is also a big savings in the time it takes to complete the installation of a vinyl liner pool.

And there is a very large ongoing savings in yearly maintenance, and chemical costs of a vinyl pool.

HOW HAS VINYL-LINER TECHNOLOGY EVOLVED IN RECENT YEARS?

Today’s vinyl-liner material is more UV resistant and isn’t easily bleached by chemically treated water. And it lasts longer. Given proper maintenance, today’s vinyl material should last 15 years or more. And we now have textured material that is meant to give you the feel of a concrete pool because some people like that textured feel instead of the smooth liner. Really, the whole purpose is to duplicate the look of a concrete pool. You have tile lines that look like concrete pools. And the vinyl-liner inks give an almost high-definition look.

WHAT FEATURES ARE BECOMING THE MOST POPULAR NOW?

Vinyl Liner Pool Builders are seeing tremendous growth in the popularity of different types of steps, benches, and especially tanning ledges. There was a time when those things were really only available in concrete/gunite. People love to sit in shallow water, and often put patio furniture in those areas. Today that’s no problem with a vinyl-liner pool.

Right now there is a growth in custom shapes. What makes all this possible is CAD technology. Before that, it was just standard shapes. Now the vinyl liner pool builder can build almost anything you want. The vinyl-liner pool isn’t what it was 15 or 20 years ago. They’ve become a living room with water.

VINYL LINER INGROUND POOL DECKS NEED EXPANSION JOINTS

VINYL LINER INGROUND POOL DECKS NEED EXPANSION JOINTS:

If you already own an inground vinyl liner pool, maybe you have seen white plastic strips placed in the concrete deck. These strips, usually called “Arrowhead” expansion joints, were placed into the wet concrete when the pool deck was installed around your vinyl liner inground pool.

They allow for expansion of the concrete and any potential movement through settling over the years. In a residential application, such as an inground vinyl liner pool, these white expansion joints are used because of the cosmetic appeal, over just a cut in the concrete, and conformity to the concrete finished edge.

These strips are a half-inch wide, 1-1/2 inches deep, and 10 feet long. They are then cut in accordance with the deck lengths and widths. They are partially tapped in with a trowel, leaving one-eight to one-quarter inch above the concrete, which allows the final deck surface to be flush with the expansion joint.

Placement of the strips is usually done based on the shape of the inground vinyl liner pool. Symmetrical-style inground vinyl liner pools, where corners and angular walls are more frequent, require more control strips in those areas. While free-form inground vinyl liner pools allow for random placement of the joints.

Most often, the strips are placed no greater than 5 to 6 feet apart in the deck, and they run from the water’s edge to the edge of the deck.

Will the use of expansion joints prevent cracking in the pool deck?  The answer is still no! Settling and movement of the soil under the concrete deck is a fact of nature, in South Jersey.

SALTWATER CHLORINATION FOR VINYL LINER POOLS

SALTWATER CHLORINATION FOR VINYL LINER POOLS

About Salt Chlorinators:

  1. It is automatic chlorine generation by the electrolysis of a small amount of salt, ordinary table salt, added to the water of vinyl liner pools. This is the first step in saltwater chlorination for vinyl liner pools.
  2. Salt level is low enough that it will normally not be tasted.
  3. The salt system generator converts salt into free chlorine which kills bacteria and algae in the vinyl pool water. Then the chlorine will reverts back to a salt solution in vinyl liner pools after killing bacteria.
  4. These reactions will continuously recycle virtually eliminating the need to add sanitizing chemicals to your vinyl pool. Except you will still need to monitor PH, Alkalinity, etc.
  5. The only time you need to add more salt to vinyl liner pools is when water is replenished due to backwashing, draining, heavy rains, or splashing, but not evaporation.
  6. As long as your pool pump is running and filtering, for the right amount of hours per day, you are in effect continuously mini-shocking your pool with fresh chlorine gas.

VINYL LINER POOL BUILDER USES POLYSTEEL WALL

VINYL LINER POOL BUILDER USES POLYSTEEL WALL

There are 3 types on inground vinyl liner swimming pool walls. One vinyl liner pool builder installs inground vinyl liner pools using POLYSTEEL as the foundation wall for the pool construction. What is POLYSTEEL? We will explain, but first let’s list the 3 types of inground vinyl liner pool walls.

GALVANIZED STEEL WALL:

The galvanized steel pool wall is stronger than Polymer-plastic wall, but galvanized steel has been known to rust and corrode. Galvanized steel is nothing more than zinc coating on the face of the steel roll that is cut and formed into an inground vinyl liner pool wall. But the edges and cutouts is where the galvanization is lost in the manufacturing process so rust starts there after the inground vinyl pool is built and filled with water. It cannot be helped with this type of inground pool wall.

POLYMER-PLASTIC WALL:

The polymer-plastic pool wall panel is sometimes called “Grafex” but all polymer-plastic wall panels are the same. While they don’t rust, they have been known to crack, due to bulging during freeze-thaw cycles in the Northeast part of the U.S. They also don’t have anywhere near the strength of steel pool wall panels.

POLYSTEEL WALL:

Polysteel is another name for polyester powder coating, that is electrostatically applied to the finished galvanized pool wall, and then baked-on in a 400 degree oven. This re-establishes the coating on all of the edges and cutouts that are made in the pool wall panel during manufacturing. Polysteel starts with a “Cardinal” 14 gauge steel wall panel, that is manufactured with G235-2.5 once per square foot coating of zinc galvanizing. Then the entire inground pool wall panel is coated and baked-on with a polyester resin, This re-establishes the corrosion resistance in areas where galvanization has been compromised, such as, skimmer cut-outs, bolt-holes, and cut edges of the galvanized pool wall panel. This vinyl liner pool builder, only installs inground vinyl pools with this POLYSTEEL pool wall.
