Air Gurgling At The Multiport Valve On My DE Filter
I have air gurgling at the multiport valve. I have a DE filter.
I have rebuilt the entire valve, replaced the body o ring on the filter, checked all of the o rings on the pump and still have the air noise.
There is no water at the site glass in the filter position.
The air noise seems to be a lot less when I move the valve to recirculate.
Thanks for the question Bob
I'd first ask you to check the Multiport (MPV) valve again. It could be the spider gasket was installed correctly, it's not seated well, or might be pinched down allowing air through the valve.
You may have put the key assembly in wrong. This can actually be put in the "new" filter position but might be in the closed or recirculate position.
You may have some kind of pump restriction. A clogged intake line or a pump or skimmer basket might be the issue.
An internal blockage such as a clogged impeller. Turn the breaker and pump motor ff. Remove the pump motor lid and basket. Stick your finger into the impeller opening. It should turn freely. Check for debris.
You can take the filter apart from the multi-port valve via the threaded unions and inspect the inlet and outlet pipes. Be sure there's no D.E. clog. Inspect the top manifold for clogs and inspect the grids as well for tears or rips.
