FTP0044 Replacement Spanner for Wrekin SLH10 and VIH10-BL Housings and LIFF NP1 and LIFF NDL2

The FTP0044 is a genuine replacement spanner covering a wide family of large housings: Wrekin's own SLH10 and VIH10-BL, plus the equivalent LIFF NP1, LIFF NDL2, BWT NP1 and BWT NDL2 models. WrekinWater supplies it with its distinctive 8-spoke design, which spreads the load evenly around the housing rather than concentrating it on one or two points. It's the tool to reach for whenever the original spanner has gone missing or a housing arrived without one.

Why you might need this

• The spanner originally supplied with your housing has been lost.
• You've bought a replacement housing without a spanner included.
• You're servicing a LIFF or BWT branded housing that shares this fitting.
• Hand grip alone won't break the seal on a stuck housing.

These larger housings rely on an 8-spoke spanner to spread the turning force evenly around the body, rather than loading up on a couple of points the way pliers or a strap wrench would. That even grip matters more on bigger housings, where uneven force is more likely to crack the plastic or round off the lugs. Having the correct spanner to hand also just makes routine servicing quicker across any of the compatible Wrekin, LIFF or BWT models.

WrekinWater is a family run company based in Bettisfield, Shropshire, that's served more than 50,000 customers over 15 years and is rated "Excellent" on Trustpilot. As the people behind the Wrekin-branded housings this spanner fits, we stock the genuine part rather than a generic substitute.

How to use it

1. Isolate the water supply feeding the housing and relieve any pressure.
2. Fit the spanner's 8 lugs into the matching slots at the base of the housing.
3. Turn anticlockwise to loosen and remove the housing for a filter or cartridge change.
4. Fit the new filter and hand-tighten the housing back into place.
5. Use the spanner for a firm final turn to seal it, without overtightening.
6. Restore the water supply and check for leaks.
