I have seen where gauges can go bad and only read ZERO. But is it possible for a pressure guage to go bad and never read correctly? My guage has seemed to be stuck on 16 lbs all summer long. My filter is a DE filter and I have only backwashed once which was back in June. Since early June the filter has continued to read 16 lbs which is one lb over the backwash reading.
I can't believe that it has never raised since last year i had to backwash probably 3-4 times. The guage will drop back to zero and also drop to around 10 when the pool slide is on. I also think that there seems to be a little bit less pressure at the returns but maybe it is just my imagination?
Can a pressure gauge be bad and give you a false reading?
