"Used to seal a hole at the bottom of a toilet cistern after taking out old overflow pipe. As this was a very old cistern with rough interior could not seal without using additional rubber washer, so 1 inside 1 outside sorted it."
"Had problem with cistern's unused bottom entry leaking. The original blanking plug washer had hardened, and was leaking. The new item fixed this problem, though I did use some sealant to make doubly sure."
"Really good quality, strongly made with an excellent sealing washer. In this case I bought it to block a hole in a wall left by an old overflow pipe, however it's use as intended for blocking/sealing a hole in a tank/cistern is excellent because of it's quality."
"I like to make sure things are fastened up nice 'n' tight, but with plastic products this can sometimes lead to stripped threads etc. This blanking plug felt really sturdy and worked a treat. Happy to recommend."
