Description
The Filter Housing Spanner – Slimline 20″ is a heavy-duty wrench designed to make removing and tightening 20″ slimline water filter housings quick, safe, and effortless.

This spanner provides the extra leverage needed to loosen stubborn housings without damaging the filter housing.
Manufactured from durable, high-strength plastic, the spanner offers a secure grip for routine filter maintenance and cartridge replacement. It is an essential tool for residential, commercial, and light industrial water filtration systems.

How to Use:
Turn off the water supply and relieve the pressure inside the filter housing before attempting to remove the sump. Position the spanner around the housing and rotate it counter-clockwise to loosen the housing. After replacing the filter cartridge, lubricate the O-ring with food-grade silicone lubricant and hand-tighten the housing. Use the spanner only for light final tightening if required. Use the spanner only to loosen or lightly tighten the housing. Over-tightening may damage the housing or O-ring and make future maintenance more difficult.
