We seem to never be able to keep a pressure gauge for very long, they seem to all sit at 0 and we get a new one and they work for awhile then go to 0.
I went to the pool store today, got a replacement. On low my pressure reads 5, on high it reads 15. Should it read the same at both high and low speeds?
I backwashed and the gauge is still sitting at 15. We have had the pool for 3 years now and this is how the gauges have always read. We backwash and the pressure never goes down.
I turn the dial to backwash
Once clean I let it continue for a few minutes
Turn to rinse
Leave it there for a few more minutes
Return to Filter
What is going on?
We have a 2 speed sand filter.
Thanks for your help!!!
