Holding Tanks and Brine Tanks

Holding tanks (or retention tanks) for chemical feed systems allow the agent you've injected more residence time to do its work. Adding retention time always improves efficiency, and with some treatments (bacteria treatment with clorine, for example) it's essential.

Brine tanks are saltwater storage tanks for use with water softeners.

Housings, Fittings, O-rings & Wrenches

Filter Housings

Filter housings for four common cartridge sizes:

Size 1 (2.5" x 9.75"), standard size for most undersink and reverse osmosis units, Size 2 (2.5" x 20") and Size 3 (4.5" x 10"), for moderate-flow whole house units, and Size 4 (4.5" x 20") for high-flow whole house filters.

Quick-Connect Fittings

We sell high quality quick-connect fittings from John Guest and G. A. Murdock, as well replacement parts for fittings.

O-Rings

O-rings ensure that housings don't leak, but they can flatten or deteriorate with time. They should be changed regularly (typically with each cartridge change) to ensure leak-free use. We offer o-rings for countertop filters, undersink filters, reverse osmosis units and more.

Filter Wrenches

Filter wrenches can help to loosen tightly screwed in housings. We offer a wide range of wrench sizes for many of the housings featured in our products. Along with standard, inexpensive plastic filter wrenches, we offer long-lasting steel Superb Wrenches.
