Verified PurchasePrompt service...As always.. good products
Verified PurchaseAgain arrived very quickly but I didn't need to install them so they are in the cupboard. On the website I wanted to buy a matched pair but this didn't seem to be an option. Would be worth making it clearer how to do this. But otherwise
A great experience!
Just email us and we will sort out a matched pair for you
Verified PurchaseAs usual, prompt and professional service from Stewart.
Very happy to recommend.
Official dealer. Valves tested in-house. 180 day warranty.
