Yes. Perhaps this is a symptom of the problem? Is the difference in pressure between filter and backwash reasonable? Seems weird that the pressure is higher when the flow is lower but I guess there is no reason for the two to be related.

Readings are: 1. In filter and recirculate - 26 psi (after backwash) 2. On waste, backwash, rinse - 12-14 psi In previous years I have usually done a backwash/rinse cycle every couple of weeks or when the pressure hits 30 psi but the pressure hasn't changed much this year - maybe because the...

Thanks - how could I test this and find out where/what the blockage is?

I am totally stumped by this issue. Here's what I've done so far: 1. Taken apart the multi-port valve - no issues, cleaned replaced gasket anyway. 2. Taken apart all the valves and cannot find any problems - no leaks (but I replaced the seals anyway), no audible indication of sucking air. 3...

As you said it was easy to remove the multi-port, however, there are no issues I can see. It is the simplest device and looks in good shape - a little cleaning with CLR and replaced the gasket and it looks like new! But no change to the jet/skimmer flow - I hope someone else can suggest...

Thanks - I'll take it off the filter and report back. I guess the issue with having low pressure/flow is that the pool water isn't filtered as much. Is there any other risk?

Hope it appears this time... Is it possible for the multi-port to be clogged/damaged just on filter and recirculate and work fine on waste and backwash? I'll try taking it apart this weekend - do I need to drain the filter first? Are there any tips / instructions - will I need a new gasket (no...

There are four valves (apart from the multi-port valve) - one is for waste so must be fine. One is before and one after the pump and must also be fine as backwash shows good pressure. The last is after the heater before the return jets - I guess this could have failed but by feel it seems to...

Yes and at skimmer. Yes - my pool water was and has been clear since opening. FC = 4ppm, CC = 0ppm, pH = 7.4, CH = 200ppm, TA = 90ppm, CYA = 30ppm

I opened my pool only a couple of weeks ago and have noticed that the pressure at the return jets and suction in the skimmer is much lower than normal. We had problems with our pool shed (floor rotted due to water) so had to get a new floor in. This involved moving the sand filter with the sand...
