First, I've been reading the forum for the past few days and it has been great to narrow our problems down.
The issue we are having in our inground pool is that our pressure has been very low (5psi).
After taking to this forum, I raised the water level, ensured that the skimmer baskets and impeller were clear, replaced the skimmer gasket, replaced the o ring in the pressure gauge but still no luck - sitting at 5 PSI with barely any water coming back into the pool.
This morning I came across a post that suggested running the pump with the filter removed. I had not heard of this so we gave it a try and bam - great pressure coming out of the jets!
My question is - is this normal to see increased pressure with no filters OR do I have a filter issue? The cartridge filters (we have 2 - a larger one and a small one that fits in the middle of the large one) are "clean" but the small filter is old - 5 years but the large filter is only a year old. My wife did use a brush to scrub the filter which we learned was a no no perhaps that has something to do with it.
Anyway, would appreciate any thoughts on what to do next. I'm thinking we have narrowed it to the filter but want to check if its normal to get an increase in pressure with filters removed.
