Hey all, I have a sand filter question. (all my info is in my signature) the filter holds 100# of sand.
I recently changed from intex fittings/plunger valves to hayward fittings. I know I have better flow than I used to have and I think my filter may be filtering better because of it.
What I have noticed though is that I feel like I am having to backwash pretty often. Right now my pool has a leaf net on it so there is nothing really big getting in there on a daily basis.
I have been vacuuming with my new pool blaster max vacuum so no vacuum junk is going through the filter.
In the past I hardly ever had to backwash. I usually only did it if I vacuumed.
Before my plumbing changes my clean pressure was 10psi and I would backwash at 12 or so.
My new clean pressure seems to be between 11 and 12. (I'm going to call it 12)
I backwashed on Saturday because the pressure was up again to around 16/17.
It went back to just under 12 after the backwash until this morning when I checked it and noticed it's back up 13.
I guess what I'm wondering is, based on the size of my pool and filter and the fact that nothing large is getting in there, how often should I have to backwash my filter? (oh yeah, my pump is still running 24/7 because I don't have a timer)
When I backwash I usually go for about 1 -1.5 minutes backwash then about 30 seconds rinse. For the first 30 seconds at the most the water is a little dirty looking and for the rest of the time it's clean.
If my filter is in need of a deep cleaning would that cause the pressure to rise more quickly between backwashes? I don't think I have ever deep cleaned it.
I'm willing (but scared) to take it apart for the deep cleaning but I was wondering if that affects the time between backwashes or just the effectiveness of the filter itself. It seems to be doing a great job and the pool is crystal clear. I have been vacuuming it every few days with the pool blaster because it's fun. lol
Thanks for any help or input you can offer!
