Hello folks
A couple of months ago I bought a Zodiac MX8 cleaner (powered by suction from skimmer, wanders randomly around the pool on tracks). When it is in use, the pool pump basket immediately starts filling up with air. This air also makes its way into the cardtridge filter housing.
As far as I can tell, the air bubbles originate below the check valve opening. I can see air bubbles rising up through the viewing window.
If I block the flow of water at the skimmer momentarily, there is an immediate effect at the pump in that lots of air appears in the basket. The skimmer is about ~16m away from the pump.
This problem existed before I got the MX8, when using just a standard brush/hose combination. It wasn't this bad. Without a cleaner attached, there is zero air coming into the pump basket, over the course of multiple days/weeks. The problem only occurs when suction is used to clean the pool.
I assume from all of the above that I have a hairline crack somewhere in the piping between the skimmer and the check valve. When there is a flow restriction on the intake, perhaps it opens up a little more and sucks air in. I am guessing. Any suggestions?
I am contemplating selling the MX8 and getting a robotic cleaner instead in order to avoid stressing the system to the point that I need to dig up piping.
