Pentair TR100 Triton II 30" Side Mount Sand In-Ground Pool Filter

My twenty-year-old sand pool filter started leaking, significantly, from an internal gasket. Good advise, imparted from experience, said, “Replace ALL of it. Those old plastic internals will be fragile”. Who can waste time or water these days?!? Excellent outcome! All the prior filter’s fittings paired up perfectly. Use a sawzall to open up the old filter’s shell, empty it with a garden trowel. One person with modest strength and capability can replace this themselves. Follow the directions! Don’t over tighten the connections. (Have a 4” capacity pair of pliers at the ready; and a small tube of silicone O-ring jelly.) Consider using glass medium (instead of sand) (it’s recycled glass and lasts longer). Earn this “merit badge”, you’ll enjoy the results.The filter was well packaged and moved easily on a furniture dolly. Delivery was a breeze and timely too. Very satisfying…

Great replacement! Ours cracked during the freeze. This was a great buy

Initially I was really excited to update my old Pentair DE filter with the Triton TR100 sand filter as I wouldn't need to buy DE powder any more making backwashing easier. I purchased the unit mid-May, had it professionally installed one week later, and now it's mid August and the filter has at least one broken lateral leaving the pool green, cloudy, and a total bummer. If you buy this filter, purchase the extended warranty as Pentair will now not provide any reimbursement for this product. Total crap. I understood Pentair to be the top-of-the-line product. I guess that is no longer the case. After paying nearly $1500 for the filter and several hundred dollars for install and glass media, I have to pay $700 for repairs and media replacement. Super annoyed!

Using this in a commercial building for cooling towers. Old one broke and I replaced it with this one and it's getting the job done. It's September 23 2022 and it's been running 24-7 since the day I received it. The filter will continue to be in service 24-7 for the rest of its life.

I have had this filter for 10 years now and it has serviced me well. The spa remains clean and the operation is quiet. Beware of one issue. The two black external manifolds, on my unit, split and had to be replaced within 5 months of each other. I'm a pretty handy guy and can fix almost anything. Replacing these manifolds require a special wrench ($150.00) to remove and/or tightening the retainer nut inside the filter housing. Even with the wrench, I couldn't remove the nut so I had to saw the manifolds off. This method worked fine but you still need the wrench for tightening. Oh yes, one other item. These plastic manifolds, manufactured in China are, at this writing, $65.00 to $85.00 each, depending where you find them on the web. Ouch

Sand filter fit perfectly since it replaced the exact same model. After 15 years the old one formed a bad crack near the lid. BTW this filter takes 500 lbs of sand or 10, 50 lbs bags.Update: 11/26/2023 Zero issues so far after over a year. Pool is clean and clear everyday.

Great filter. Easy to set up.

We changed from a 250 lbs filter to a 600 lbs filter. Made a big difference in how clean our pool stays.
