Great Filter..and Great Customer Service from Discounted Pool Supply!

Reviewed in the United States on July 9, 2022

Style: OldVerified Purchase

First of all, I am a big fan of DE filters. I think they do the best job with filtration, and I don't find cleaning mine twice a year to be a big chore...in fact I find it way easier than cleaning out every little pleat in a cartridge filter system. This filter replaced the earlier model pentair, which had a fiberglass lid failure after 23 years of service. The new filter appears studier and is easier to clean, but for the most part is the same, and I hope I get 23 years out of this one too!

The other thing I wanted to call out was the excellent service I received from Discounted Pool Supply. They shipped the filter to me quickly, but I later found a small but essential part to be missing. I suspect the error happened at the Pentair factory. When I reached out to Discounted Pool Supply, the communication was great, and they FedEx'd the missing part to me with overnight delivery. Now that's service! I find great service is hard to find anywhere these days, especially in the pool business. I would not hesitate to buy from them again, knowing they value their customers and stand behind their products. Bravo!

Replacement - Perfect

Reviewed in the United States on May 9, 2020

Style: OldVerified Purchase

This is a replacement for tank we have had for 20 years. Arrived fast new in box. My only complaint was that the delivery was supposed to call us and set up. They did not call or contact. Arrived quicker than delivery date indicated. Gate was closed and they left it outside our gate by street. Almost $900 item left by street. My daughter just happened to come over and couldn't get the gate open because the heave box in front of gate. We were inside gate and couldn't get out as the box was against the gate. Fortunate it wasn't stolen. We didn't know it was there. Had to call neighbor to come move it enough to get the gate open. Other than deliver, it is perfect and works great. Easy to install replacement.

Good filter, one bad engineering flaw!

Reviewed in the United States on May 1, 2023

Style: OldVerified Purchase

Overall this is a great filter with one dumb flaw. They placed the drain plug directly underneath the outlet pipe with no room to add any extensions or valves. So if you need to drain it, it will drain right there with no way to attach a hose. Terrible design!

SERIOUS PACKAGING PROBLEMS !!!

Reviewed in the United States on March 10, 2014

Style: OldVerified Purchase

The filter itself is a good quality product but the FIRST one we ordered came predictably broken due to unbelievably pathetic packaging for such an expensive piece of equipment. NO PADDING ANYWHERE for an 80# ungainly,hard to gently move around box; the bottom (base)was broken. We returned that one for a replacement and when the new one came,the pressure guage(dangling unprotected inside the box in a plastic bag) was crushed.Back that one went because they coudln't just send a new guage(?) . The THIRD one came,and guess what, THAT guage was also broken !!??!! because no one had bothered to correct the pkging problem after it was pointed out the 1st time.(INCREDIBLE !) So in the end they sent a new guage to put on the second filter that wasn't completely broken and now our pool is finally up and running again( after having to wait 3 weeks for UNBROKEN PARTS) .AMAZON made it right ( but PENTAIR needs to rethink their shipping/packaging problem before I would ever recommend anyone buy their product and put themselves in for the grief we went through) . Amazon temporarily suspended sales for this reason and their customer service to correct this was commendable

An easy fix for an older system

Reviewed in the United States on May 24, 2020

Style: OldVerified Purchase

I replaced a crappy Jacuzzi diatom. filter that leaked and had a pot metal lock ring that froze up and would not come apart to clean. It took about 45 minutes to install this one, that's including the time it took to cut out and remove the old one. Rock solid, easy take-apart for cleaning, a piece of cake to install. You will need to buy the Pentair pipe-adapters to attach the 2" Sch. 40 PVC pool plumbing to the filter, or buy a pre-made manifold if you want one, they're sold separately.

Pentair DE Filter

Reviewed in the United States on June 29, 2019

Style: OldVerified Purchase

Felt obligated. I was tired of a cloudy pool. I had an undersized cartridge filter that just wasn't cutting it. After doing some research, decided to go with the Pentair DE 48" filter. Had to do some PVC work due to changing filter types but it wasn't too bad. Once installation was complete, I mixed and added about 5lbs of DE. Let the pump run for 2 days. Checked on it on the 3rd day and was a little disappointed in the results. The pool was a little clearer but not much. I wasn't sure if I needed to add more DE or not. Figured I would leave it be a few more days. Couple days later, the pool was crystal clear. It has stayed crystal clear. This filter does an amazing job. It's been almost a month and I could not be happier with the results. My pool is a 20K gallon and this filter exceeds expectations. If your on the fence, I'd say leap!

More than/Less than OR Just As Expected

More than Expected - Yahoo!

Reviewed in the United States on September 20, 2018

Style: OldVerified Purchase

Our Pool Filter was the same model Pentair and that one was at least 11 years old as it was here when we bought the house. Its real age was hard to determine but it wasn't brand new when we got into this house. PERFECT - EASY Replacement. No modifications needed for a swap out at all! I slide the old unit out, put the new base unit in place, tighten the plumbing fixture to the filter base, out the filter back into one complete unit and started the pool up! Easy Peasy! Hope this one last for another 11 plus years! It has a few modification to the internal works so it looks like it will without any problem. Its been running every day for the past 5 months without ANY issues.
