I caught up with the customer (who is the subject of this thread) and he said a leak detector came out and, by pressure testing the suction side plumbing, found an air leak in a loose non-return valve that was buried at the front of the pump inlet. The problem was solved but left a question...

Hi all, I had a call from a past customer who couldn't get his pump to prime. I installed a new pump about 2 months ago and after that he said he would take over the servicing. Pump is about 2.5 feet above water level When I attended I: Checked all valves open and sand filter on filter...

Done. 4 kg (1.8 lbs,?) Of Buffer is in the pool. The roof runoff isn't the problem as it hasn't been diverted in to the pool for months.

I thought low TA caused swings in ph but never considered that just having unbalanced TA would do the same. That would make sense in his case. I'll tell him to get some bicarb and get the TA up. Thanks Marty. - - - Updated - - - Up the road from me in Australia. Need to update my sig :)

His pool is always full, even above the skimmer. And most of that fill water is from rain. I'll see if we can test the roof runoff and I'll encourage him to get a decent test kit. Thanks.

Thanks Marty, I edited post to add cya. I overlooked it. I will go back over those links you suggested. The real brain scratcher was the consistently low ph even though running a salt water chlorinator which traditionally pushed pH up over time. I can't seem to figure that bit out.

Hi, I am trying to help my brother in law with his pool but it has me stumped as his chlorine is consistently low as is his pH. It's a 17000 gallon concrete in ground pool that has been resurfaced with fibreglass. He runs a 1 HP pump, 25 gram chlorinator and sand filter. The chlorinator is...
