Water Filter Wrenches

A water filter wrench is a special tool designed to fit around the base of a water filter housing, making it easy to loosen the plastic sump that holds the filter cartridge. Having a quality wrench in the right size for your water filter system makes changing the cartridge simple and helps eliminate leaks. If you aren’t sure which wrench you need, call our Certified Water Specialists at 1-800-608-8792.

When you have an appropriately sized water filter wrench, removing the plastic housing sump that holds the filter cartridges in your system becomes much easier. Before you purchase any wrench for your filter system, you’ll need to know the diameter of the housing and how many grooves it has so that you can find the best tool for your needs.

When using a water filter wrench on any system, it’s important to be careful and not put too much stress on the tool. It’s a good idea to lubricate the threads that hold the sump to the filter housing top so that it will be easier to remove when you need to change the filter. When attaching the sump to the housing top, be careful to not overtighten it, as you could damage the o-ring on the sump and make it extremely difficult to remove.
