Sand Filter Getting Air

[hrsdennis]

#20 silica is fine. A rule of thumb for backflushing is about two minutes or untill the water come out clear.

After you backflush does the filter start out at 20lbs or does it start closer to 10 and then climbs quickly? If so how quickly?

It usually starts out at about 14 and climbs over the next hour or two.

It sounds like the filter is getting clogged with dirt or algea. You may just need to backflush every few hours until the water gets cleaned up. If you are filtering clean water I think we are back to changing the sand.

That's about it for my ideas, best of luck, Dennis

Thanks so much. I will do that.

The most common place for an air leak is the lid to the hair and lint pot

I had to replace my lint pot lid due to a small crack that had developed - it was along a natural seam and was difficult to spot at first. I was also experiencing reduced pressure problems - and kept going back to the lid, until I finally spotted the problem.

I have read this thread with great interest, since I have a 24 foor round AGP and have some questions about my sand fiter. Sounds like you are the people I need to talk to...

I have a Baquapure 2600 sand filter with a 2.5 hp pump. I don't seem to have any leaks or air issues, but I just have this feeling that my filter is not working as well as I think it should be. I backflush like you decribed above (a couple of minutes, till outlet water is clear) a couple of times a week, but my gauge always seems to hover around 19-20 psi. I replaced the sand last summer, but have had a lot of algae problems this spring (we live in Florida, so the algae starts blooming in about March). What pressure should the gauge read in normal operation? If it is higher than it should be, what is the proper drill to get it back in the right range?

Thanks for any help you can offer.
