Automatic Vent Seal Repairs

5 star review(5/5)
This is an original part and as such of excellent quality. It comes with a set of picture instructions that are mostly easy to follow although the diagrams show the job being done with bare hands. Disposable gloves are a necessity. The whole unit is easy enough to remove with a quarter turn as shown but the diagram does not make clear how the the 'sponge' damper is removed. This also requires a quarter turn to disengage. The seals can then be easily replaced. In the event I suspect that these did not require replacing in my case as the automatic vent was actually stuck in the open position thus causing the leak. Silicone lubricant applied down the shaft cured this so check this operates correctly before changing the seals.
