I am a new pool owner this season, and have had difficulty keeping the pressure steady. The starting pressure is 9psi, and sometimes after a backwash it is steady for a few days, and other times it spikes within an hour or so.
This week, for example, I added chemical to remove metal staining, then back washed and refilled with proper amount of DE. After a few hours, the pressure jumps to 25psi and there is some dripping of water from under the top cover of the filter. There is no dripping when the pressure is stable.
I had the filter acid washed, and have probably had to backwash 6 times already this season which seems excessive. Water is clear, chlorine at 1, other levels balanced. No algae in pool. Hayward 1HP new pump and previous owners Hawyard DE filter.
After consulting with several pool owners and companies I have not gotten the same piece of advice twice, which is frustrating! Any advice is much appreciated!
