DE Filter Sizing

[Mcb]

Hello,

I believe that it is time to replace my DE filter. I'm trying to determine the proper size. What is the rule of thumb?

Is your current one filtering sufficiently? Why does it need replacing?

Which model is your current one?

MCB,

4000 is a series number so you have either a 4024, 36, 48, or 60 Sq. ft. filter

You can never go too big so I would get the 4060, but certainly not less than what you have now...

The larger the filter the longer between backwashing and cleaning.

I never backwash anymore, I just break the units down and clean then them twice a year..

Thanks,

Jim R.

For your size pool, the 36 sqft should be sufficient. But, given the pool being open year round and wanting to clean it as few times as possible, bigger would be better.

I have the 4000 model. I was thinking about replacing it because the band is bad. The metal coupling is breaking and I can't tighten it enough to tighten the whole unit. I am seeing that a new one is $300. I also have a small leak on the backwash valves. So, i'm wondering if I'm already half way to a new unit that I'd be better getting a new one.. Only owned the home for a year and I wasn't sure if it was sized bigger than I needed. than needed.

The 4000 is the series. Does the unit have a model number as described by Jim above?

 

[Mcb]

i'll have to look at the model, but its a 48 sq inch

 

[mknauss]

Great. So a 4048. How often do you have to back wash each year?

Based on Jason's response sounds like you just replace with the same if you want. But again, replacement of parts may be sufficient.

 

[Mcb]

I've owned the home a year. Back washed it twice. This is the first time I cleaned the grids.

 

[Mcb]

Where is a good place to find parts and part numbers. I'm having no luck.
