Hi all,
I recently installed a Hansgrohe select concealed shower valve. I set the max water temperature as per instructions, I set it just over 40 degrees, about 42. The shower has been in use a month or so and was fine. But a few days ago I noticed it wasn’t getting up to temperature, it was only tepid on maximum. Checked water temp at basin and that was nice and hot so today I took the valve apart to check the cartridge etc, as I wondered if any debris had got in there from the new plumbing I did which is all copper with soldered joints. Other than a small amount of grit it all appeared in order, from what I could see anyway, the cartridge doesn’t appear to be serviceable other than the o rings. So I’ve built it back up and adjusted the temperature again, it is now set at maximum but only just achieves 40 degrees. For reference I checked the basin hot water temp and that was 51 degrees. Now 40 degrees is enough, I do prefer it more like 42, but I’m nearly sure when I first installed it I had to turn the temperature down as it was too hot. So I’m wondering if the thermostatic valve is faulty in any way ? Just seem odd that it was fine and then all of a sudden it wouldn’t get hot. I bought the valve off eBay from a private seller, it was brand new but obviously won’t have any warranty. Any help much appreciated. Andy
