GBGreat product. Brilliant seller
The item arrived damaged after a hard time through the postal service. When I told Matt about it, he immediately sent a replacement which arrived next day! The flapper valve was easy and straightforward to fit. I just had to trim the overflow tube. It was installed quickly and is working well. Overall: Excellent service. Very pleased. Many thanks
