"Just the job. Needed a replacement for the 1970's rotted fitting on a very old WC flush pipe. This was ideal. A touch of silicone grease on the fins and on the flush pipe and job done! No leaks, no dramas and quietly impressed clients"
Only bought it as a last resort as my merchant was out of stock of proper rubber ones.
Had to do exactly the same as previous reviewer.. ie. clean up the original one and silicone it in place. This one was popping out and could have easily flooded the customers house. An accident waiting to happen, don't risk it.
The toilet manufacturers/suppliers ought to stop sending out these useless plastic ones too."
