Replacing old DE filter

[wcodyd]

Friends,

I have a 30K gallon salt water pool with liner. The pool was built before we purchased the home. I suspect the pool is ~15-20 years old. I’ve already replaced the pump, and now I’d like to replace the DE filter.

The current filter is a Hayward DE-3600. I’ve already replaced the valve and the filter fins. The current problem is it doesn’t filter well and when I add DE to the skimmers, most all of the DE ends up back in the pool (on the floor). I suspect I have a cracked manifold or some other issue.

I’m attaching a picture of the current set up. Would you recommend a new filter? If so, which one? I’m thinking about the Hayward DEP 100. I have a budget of around $1,000. I mainly want low maintenance, effective filtering, and long-term value.

Thank you.

Consider a cartridge filter. The biggest you can afford and fit on your equipment pad. Probably get away with cleaning it once or twice a year if sized appropriately. Pentair Clean and Clear Plus are good filters. They are in short supply due to the overall pool equipment shortage.

Low maintenance and a $1000 budget, i would buy a 500lb sand filter and a prefilter cyclone.

Thank you for the replies. I like the idea of a cartridge filter — seems that would be a little easier than what I have now. I will increase budget if needed to get the best long term value. What about the Hayward brand cartridge filters? I’ve been looking at a Hayward W3C5030 cartridge filter.

Filters are pretty universal. If that filter looks good for your situation, it will work fine.

After researching this more, I’m starting to wonder if it makes more sense to replace my multi port valve and guts (manifold and grids) on the DE filter. What is the new equivalent to the Hayward SP0710G11M?
