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

BRUCE R. ROACHE  Pool Leak Detection & Repair  860-355-3202


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 serious 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 to the wall structure, undermine the bottom, or damage a liner beyond repair.  NEVER ALLOW A POOL TO DRAIN DOWN LOW OR EMPTY!


Do You Have A Leak?

The first thing to do is carefully mark the pool water level, wait 24 hours, check it again and measure how much it dropped.  (perform 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 & NY

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

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

When I inspect a pool for loss, 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.  Call for a full inspection so all the leaks can be found and fixed.

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

Same Loss Filter On or Off =               Points toward a leak in the pool, less likely to be in pipes

Much Larger Loss With Filter ON =     Points toward a leak in the return piping or backwash

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

Air Bubbles In The Return Water Flow:

Air in the return water flow can be a sign of a broken suction pipe (skimmer or main) but most often it is an air leak in the gaskets, valves and piping prior to the pump 


Leaks Do Not Fix Themselves!

Call for service before serious damage occurs to your pool and property.
