Rated 5 out of 5 by from Sealed Small Radiator Leak Poured into radiator which had a small leak using a hose and a funnel via the air vent hole. Refilled the system ran it and the leak was sealed. No problem. Cost effective and value for money.

Rated 5 out of 5 by from excellent product for a reasonable price i have 15 radiator heating system with copper and PVC pipes. i was having dropped pressure issues for few months which got worse over last couple of months. The system would loose pressure every week and half or so. I added the leak sealer via towel rail, about 3 weeks ago. i have not lost any pressure since then. The pressure seem to go a bit too high initially after adding the sealer but have not stabalised now. a really good product.

Rated 5 out of 5 by from Heating Engineer Used this many times and never had a call-back, wouldn't use anything else, perfect for weeping joints and leaking rad valves anywhere on the system.

Rated 5 out of 5 by from Easy to add to systems Easy to add to a drained system, was a bit sludgier to add than a product such as X100 but presented no challenges to do so. Would recommend.
