Where is the air coming from?
This is a continuation of a previous post about maintaining chlorine levels. I wasn't sure how to link post so I'm repeating some of my post.
We live in North East, Nassau County LI and didn't have trouble for the previous 18 yrs. A few yrs. ago we had the liner replaced.
Rainbow in-line feeder (recently cleaned)
1 1/2 in. pipe
1.5 hp pump, just replaced - new
DE filter - 48 sq. in.
Our in-line chlorinator wasn't working and then Scott cleared up the mystery. We had air in the system. After back washing the system began working and so did the chlorinator but only for about a week. Then the air was back. Someone suggested putting shaving cream around areas that could be leaking - sucking in air. DH did that and nothing. Its a new pump. Well after back washing, again no air coming out of return or in pump and chlorinator working. Then I used my polaris cleaner. No problem when the pump went off/on with polaris(timer overnight). After I shut off polaris while pump was running it was ok. In the morning there was air again coming out of the return and in the pump basket. When the air is present the chlorinator is not working, which Scott explained in previous post. Could the polaris be the cause or is it a coincidence? What could it be? We are not losing water, other than evaporation.
