The LavaTap Flex Seal Rubber Coupler is an essential plumbing component for professional contractors and DIY enthusiasts who need to join 110mm waste and soil pipes reliably. Its primary benefit lies in its flexible material composition, which allows for quick connections between disparate pipe materials such as plastic, cast iron, and steel while accounting for minor alignment errors. While it provides an excellent seal, users must ensure the pipe surfaces are clean and debris-free before installation to guarantee a watertight result in challenging, tight spaces.

Ensure the jubilee clips are tightened sufficiently and check that the coupling is centered equally over both pipe ends.
Loosen the clips, clean any debris or sealant residue from the pipe surface, reposition the rubber sleeve, and tighten the clips again.
For care, periodically inspect the jubilee clips for signs of oxidation if located in high-moisture environments. Ensure no heavy objects are pressing against the coupling that might create an uneven seal over time.
