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

The Pentair Triton II is the original side mount sand filter and still the industry standard. The TR100 is the 30 in. tank, sold here without the valve so you can pair it with the side mount valve your plumbing calls for.

The tank

Pentair molds the Triton II as a one piece, fiberglass reinforced tank with a UV resistant surface finish. The process locks the fiberglass in place, which stops fibers from blooming under harsh conditions and gives the tank years of strength and durability.

Service features

A heavy duty closure opens for inspection and gives instant access to the sand and all internal parts. The easy to read pressure gauge carries an air relief valve, an internal air bleed automatically prevents air pockets, and the combination sand and water drain makes servicing and winterizing fast.
