Never drain a pool, Severe damage will occur if it is empty!   All my leak repairs are done with the pool full.

If you add more than 1" of water per week,  YOU HAVE A LEAK!

Call for service so I can quickly find and fix all the leaks and prevent damage to your pool.  A leak as small as 1/4" per day from an average 16 x 32 pool will leak 29,200 gallons / year!  Always check your pool level for loss before closing it in the fall.  Leaks that go unrepaired can cause severe damage.  NEVER ALLOW A POOL TO DRAIN DOWN LOW OR EMPTY!


Do You Have A Leak?

The first thing, carefully mark the pool water level, wait 24 hours, check it again and measure how much it dropped.   (test on a day with no rain, do not backwash, avoid excessive swimmer splashout and make sure the autofill is off)

Normal Evaporation in CT Area

Normal evaporation in 24 hours is 1/8" per day, covered pools: 1/16" per day, Pools with waterfalls and pools heated far above the air temperature can lose 1/4" per day

Is The Leak In The Pipes, The Pool, or Both?

I check: the entire underwater surface, test the pipes, inspect the lights, hydro valves, stairs, seals, gaskets, fittings, screws and skimmer housings.  Most times it is a combination of several small leaks.  A full inspection will find all the leaks.

24 Hour Test: Filter On vs 24 Hours With It Off:

Same Loss Filter On or Off =      Likely a leak in the pool, less likely in pipes

Much Larger Loss Filter ON =    Indicates leak in the return pipe or backwash

Larger Loss With Filter OFF =    Indicates leak in a suction pipe (skimmer or main)

Air Bubbles In Return Water Flow:

Air in the return water flow can be a broken skimmer or main pipe,  BUT most often is an air leak in the gaskets, valves and piping prior to the pump
