Can this pressure gauge be calibrated. When the pump is not running, the gauge reads 11 - 12 psi, when the pump is running it reads slightly over 22 psi. When the water is diverted to the slide, the psi is about 21.5 psi. We recently replaced the lid to the filter and cleaned the cartridges. The filter is about 10 years old. Is it time to replace the gauge?
