[What Should the Pool Filter Pressure Gauge Read?]

Ideally your pressure sits somewhere between 15-20 PSI so there is good circulation without too much pressure on pipe fittings and equipment. However it is common for pressure gauges exposed to teh elements to fail and read wrong. Some people replace their gauges yearly, others learn to use them with the new readings. Most manufacturers suggest cleaning or backwashing the filter when pressure is 10 PSI higher then normal. Note that a high backpressure can reduce teh efficiency of the filter as well.

Since the pool is only one month old, and the guage was replaced just in case it was bad (it wasn't), then it seems that that pressure is too high. You mentioned that 15-20 PSI would be ideal. My pool is at 30-40 PSI, depending on whether I bypass the heater or not. So I guess you are saying that the pressure is not normal for a new pool.

[What Should the Pool Filter Pressure Gauge Read?]

We have a new inground pool with an in-floor cleaning system, spa fountain, and waterfall. As the system cycles through the various cleaning zone, the filter (4 cartridges) pressure gauge varies from 30 to 38 pounds. I've been told that it ought to be 10-15 psi. Is this correct? The filter cartridges are new. Do I have a problem with the piping?
