"had an existing TRV that had broken, but the value part seemed OK. Bought this to replace the top part, hoping it would fit. It did, amazing, 99p plumbing fix. Now I can stop using a clamp to control the heating!"
"Very good product in every way, in this price bracket. Even better value at this give away cost. Used before and purchased these to have as replacements if needed. For me, everything about this valve is right. recommended."
