Why is my pool sand filter pressure so high?

Dale Kreviazuk

There are various reasons that a sand filter pressure is high, such as:
  • Your filter may need to be backwashed.
  • The drains in your filter could be heat damaged from turning off the pump while the gas heater is running.
  • The gauge might be frost damaged from not being removed during Winnipeg winters. This frost damage may cause the gauge to max out and be permanently damaged. Luckily, new gauges are under $10, and can be replaced in less than 5 minutes.
