Rated 5 out of 5 by Ideal for sweaty joints Had a towel warmer with a valve that was slightly "sweating". Put this in the system, job done! It's similar to a PVA consistency so you need a funnel, or the filling kit (89062) to apply. 4 Jul 2015
Rated 5 out of 5 by leak sealant I got this product after reading the reviews and yes it works great. I had a leak on a back boiler when I changed the pump and didn't want to remove the gas fire to gain access so I tried this and in ten mins the leak had stopped. Give it a go and it will sort your problem out. 29 Jun 2015
Rated 5 out of 5 by Works fast Needing to replace a heating element in a towel rail , an isolating valve started to leak when I tried to close it. The valve had been leaking for about 2 hours , but stopped within minutes of adding this product to the system. 8 Jun 2015
Rated 5 out of 5 by Saved my bacon I had a leak in my central heating system, the leak was under the concrete floor so using No Nonsense Central Heating Leak Sealer was worth a try. I'm pleased to say that 'so far so good' it has done the trick. I've marked down on the 'Reliability' as it's only been in the system for 2 days. 21 May 2015
