QuickFill - SEL9260: Central Heating Dosing Tool - Add Chemicals Like Fernox Central Heating Inhibitor, Sludge Remover, Leak Sealer & Sentinel X100 to Your Central Heating System

Purchased this and the drain bowl at the same time. Needed to drain a radiator in my caravan to top up the anti freeze in the system. These work great. Not one drop went on the carpet when using the drain bowl, and refil was easy with the bolt on dosing tool. Saved a fortune using these instead of paying a plumber.

Clever way to fill up your radiator circuit with system inhibitors. Easy to use follow instructions. Good price.

Good value and less hassle than making one yourself from various component's

Good product at a good price

Great tool for putting inhibitor in the central heating system, very easy to use and not expensive

Makes adding solutions to radiator much easier.

Very pleased with the quality and product

Works fine, however I'd recommend you add a rubber washer to get a tight seal and avoid scratching your radiator. I added a rubber washer and used it to add inhibitor, silencer and leak sealer to my system with no problems. It's very exoensive for a bit of plastic and a threaded fitting and I really think it should come fitted with a washer already for the price.
