    Pool Openings


    When using The Three Cousins, you can be rest assured that a trained technician with years of experience will be opening your pool and they can handle any situation that comes up.  Some pool openings are very basic (one pump, one filter), however many pools consist of multiple components. 

    Oftentimes, there are complex setups with multiple pumps, filters, heaters, waterfalls, salt water systems, laminar effects, sheer descents, slides, UV systems, automated systems, and other elements that our technicians are equipped to handle. 

    Who wants to answer a hundred questions about their pool when you hired someone to open it?  We try to stay current with the latest pool equipment and supplies to make the opening experience easier for you, the customer.

    A typical pool opening includes the following:

    • Professional removal and fan folding of cover for summer storage (any excess water and/or debris/leaves on top of cover prior to pool opening will result in additional charges).
    • Cover is placed in shed, garage or other location where customer prefers
    • Plugs & skimmer gizmos are removed and system is primed with water
    • Return eyeballs, skimmer baskets, and any drain plugs installed
    • Filter site is assembled and tested for any leaks. Pump, filters, chlorinator and any other components are connected. O-rings & gaskets are lubricated to maintain a water-tight seal
    • Once the system is up and running we will add the initial chemicals as well as DE, if you have a DE filter
    • Hand-rails, diving boards, & ladders will be installed and checked for safety. On above ground pools, we suggest putting the stairs/ladder in after the pool is vacuumed
    • Once the system is running with chemicals, our technicians will advise if there are any issues.  Typically the next step is to Power Vacuum the pool.

    Salt Water Conversion

    Call or text today (516) 543-1297

    Salt Water Pools


    We like to think of ourselves as “salt water experts” at The Three Cousins.  We were installing salt water systems long before it was trendy.  The pros typically outweigh the cons, but if you would like a quote or more information, we offer free estimates.  Most salt water chlorinators are compatible with your existing equipment.

    This means that you do not need to buy a new pump or new filter to convert to salt water.  The salt water system is connected into your plumbing, oftentimes replacing chlorinators that used to hold tablets.

    The chlorinator gets power from being wired into your existing timer at the filter site.  In some cases, an electrician may be needed to wire the system, for example when the timer is in the garage or basement.

    How does it work?

    There is a misconception that salt water pools do not contain chlorine.  This is false.  A salt water pool sanitizes the water with chlorine, just like a pool with chlorine tablets.  The key difference between them is how this chlorine is mixed into the water.  Salt chlorine generators, or chlorination systems, convert sodium chloride, NaCl, into chlorine.

    NaCl is essentially table salt.  The key component in the salt system is the salt cell and it works by electrolysis.  The salt water is electrically charged, which splits the alt molecules and generates chlorine, Cl.  This is basic chemistry. The salt generator, or salt water system, has 2 main components; the salt cell and the power center.

    The salt cell is plumbed into your pipes so that water flows through it.  As water passes through the cell, it goes through metal blades coated with ruthenium or iridium.

    The metals are charged by the power center, which gives the electricity for the electrolysis process.  Some power centers even have a control panel, where the user can adjust the chlorine output and read diagnostics.  The salt level is normally kept around 3000 ppm, or parts per million, for optimal performance.



    Salt Water Maintenance


    Another misconception is that salt water systems require zero maintenance.  This is also false.  Salt water pools are relatively maintenance-free, but you should always be checking chemicals on a regular basis for the safety of everyone using the pool.  You will also need to add salt throughout the pool season.  Typically salt is added at the beginning of the season, after power vacuuming, and intermittently throughout the season as rain water dilutes your salt level.  We make sure to keep our salt levels accurate as part of our weekly maintenance.  One other element of salt system maintenance is cleaning your salt cell.  From time to time, calcium and other minerals can build up on the metal blades, impeding performance of your salt system.  This can be cleaned with acid or salt system cleaning solutions.

    Benefits of a Salt Water Conversion

    • Easy to control the amount of chlorine in the water
    • Doesn’t have strong chlorine odor 
    • Water has less harsh chemicals and is much softer on skin
    • Won’t bleach hair or clothing
    • Salt water pools is 1/10th the salinity of ocean water, not that salty
    • Less maintenance
    • Less irritation on eyes
    • Good for people with sensitive skin
    • Lower chlorine levels
    • Save money on chemicals - no more expensive, heavy tabs

    Service calls and Plumbing


    The unfortunate truth is that sitting all winter is not good for pool equipment, even if kept in the garage or shed.  Most of the components in your pool system are designed to have water running through them constantly, so sitting dry can on occasion cause issues.

    Sometimes when we open a pool, a pump that worked last season doesn’t work.  Other times, you might see something leak that didn’t used to leak.

    Our technicians are trained to handle most situations that we might encounter, so usually we can address most of these issues on the spot.

    If we can bring your pump back to life, we will! But in the circumstances where something is broken or needs to be replaced, we can handle that also.

    Our prices are reasonable and our senior technicians can fix even the most difficult pools.  We will work to get you an estimate and get you on the schedule quickly so you don’t lose valuable summer days.



    Pool Closings

    Pool Closings


    When using The Three Cousins, you can be rest assured that a trained technician with years of experience will be closing your pool and they can handle any situation that comes up.  Some pool closings are very basic (one pump, one filter), however many pools consist of multiple components.

    Oftentimes, there are complex setups with multiple pumps, filters, heaters, waterfalls, salt water systems, laminar effects, sheer descents, slides, UV systems, automated systems, and other elements that our technicians are equipped to handle.

    Your pool equipment is valuable and we strive to make sure everything is winterized properly  This ensures your equipment lasts as long as it can.  We also don’t mess around when it comes to blowing out your pipes.  We use commercial blowers to ensure each line is cleared and then we add antifreeze as an extra precaution.
