Rated 3 out of 5 by Time Will Tell ? Being in the trade I normally buy more expensive valves but thought I would give these a try. Bought two sets of these for a job but after three days one of the Thermostatic valves leaked through the spindle, so cost me time and money having to drain the system again (install more inhibitor) and return to screwfix twice, once to collect a new valve and once to return the faulty one. Only glad that the customer found the leak and it didn't cause any damage. 21 Jan 2016
Rated 5 out of 5 by Good product Theses TRV are not what I would normally buy, usually use a plumbers merchants for TRV's but tried these and like them. 17 Jan 2016
Rated 5 out of 5 by Fantastic product! After a plumber failed to turn up I had no choice but to replace the valves my self. Im pleased now I did and saved cash too. Fantastic product, looks great and happy with the price. Heatings back on and I'm definitely going to replace the lot now. 15 Jan 2016

Reading the instructions it states install "by following the flow direction arrow on the body". However, on the body of the valve there are two arrows pointing in opposite directions. The one on valve arm points into the radiator the one taking the 15mm copper tails points away from the radiator they both cannot be right as water must flow in one direction through the valve. At the moment I have guessed that it should be on the feed side. Is this wrong and does it matter which side feed or return the valve goes on?
Would be helpful if the company had a telephone number/tech support.

All our properties have Myson TRV angled two way valves and these go from time to time. My local stockists doesn't keep them anymore. Would this model be a suitable replacement? Please advise.

Kind regards,
