48Sq Ft to 60Sq Ft upgrade - couple of questions

Hi All,

I upgraded our DE filter from the Hayward 48sq ft to the 60sq feet and want to get some thoughts and feedback based on what I am seeing -

1. The starting pressure after charging the system with DE seems to be a bit higher with the 60sq ft (around 23) compared to the 48sq ft (around 21) - I expected this to be a bit lower and want to ask if this is normal
2. I believe having a larger capacity filter should increase my interval of backwash and filter break-down and cleaning - Would that be a correct assumption if anybody has gone through this journey before?

Thanks for your replies!
Ram.

Ram,

I would have thought the same thing... I doubt there would have been much of an impact, but I would have thought the larger filter would have had a little less resistance to flow.

I never backwash any more... I have two rent house pools with DE filters.. One 48 sq.ft. and one 60 sq.ft. I run the pumps at 1200 RPM most of the time and clean them twice a year, in the Spring and then again in the Fall... It has made my life easy... And, my clean filter pressure is about 4 or 5 lbs.. So you must be running close to 2800 or 3K to have a pressure over 20...

Why???

Thanks,

Jim R.

Hi Jim,

Thanks for your response. Yes, the pressure of 23 is when I am running the pump at max rpm - 3250. I never run it at that rpm unless I am trying to recharge the system. I run the pump 24 hrs. For most of that time - about 20 hours, it is running at 1500 rpm with a pressure of around 6(just checked it now). During the rest of the time - about 4 hours I run it at 2500 rpm. This is also when I run the booster for cleaning.

The comparison I had was at peak rpm filter to filter.

I am hoping I can do what you are able to do where I do not need to backwash, but just breakdown clean twice a year. That would be nice :).

I should be ok with what I am seeing at lower rpm. Will see how it goes.

Thanks!
Ram.
