Low Pressure On Sand Filter

[malo52]

Hi,

Hopefully someone can help me out on this issues I'm having. Looked at a bunch of videos to trouble shoot the issue but to no avail.

Some background information started right when i opened the pool.

In Ground pool.
Salt Water
Raypack Heater
Pentair Superflow VS pump
Hayward Sand Filter pro series.

All about 6 years old.

Issue: pump primes no air bubbles seen in the pump. When pump is shut off pressure is still there. When the pump turns on, pump fully primed. but the guage on the sand filter is almost zero. Also the flow to the return jets is very weak and notice little air bubbles. I cleaned the skimmer basket, pump basket, checked pump impeller. pool water level is fine. the pump is set to 1800.

any help would be most welcomed.!!!!!!!!!!!!

Could be a faulty pressure gauge
