Leaks And How To Diagnose And Repair Them – Part 2

Whilst we have been enjoying some rain this winter, and the dams are above 50%, the end of water restrictions pertaining to pool owners is not something that will be changed anytime soon.

The second most common leak encountered by pool owners is the return leak

This leak does not have any visible symptoms like the suction leak.

Being on the return circuit/side of the pool system, it does not affect the overall performance of the pool cleaner or pump.

This leaves only one symptom, and that is water loss.

This very simple 5-minute check could save you thousands of liters of water.

This kind of leak can originate from either end of the return line, either at the pump or at the fitting which connects to the aimflow fitting, located directly behind it, underground.

The leak at the fitting behind the aimflow is often a very big job, especially if the pool has a thick foundation wall, which limits access to the fitting.

When this happens, it’s best to core either a new hole through the pool wall or core out the existing fitting. This then allows the Technicians to slide in a new piece of PVC pipe and attach the fitting

It may also leak around the inside of the pool through and or around the actual aimflow fitting.

An easy way to determine this is to purchase some colourful dye, squirt the dye around the fitting and if it’s sucked into the fitting, then you have an answer.

The only real way to determine whether you have a leak on the return line is to do the following:

Block off the current one.

Disconnect the current return line from the MPV housing.

Connect a temporary above ground line from the system to the pool.

Monitor the water loss.

If the water level remains stable, then you have your answer.
