– Central Heating System Plug Kit - Eliminates the Need to Drain - Includes Tank Cap and Essential Tools

Spot on. did the trick. Fit perfect. Another trick I've learned. Prob never have to use them again but well worth the money.

Perfect, did the job. Less spillage whilst installing trv valves.

Great for using to bung feed and expansion tank pipes, enabling me to create a vacuum in heating system long enough to change a couple of radiator valves without too much water escaping and avoiding need to drain entire system. These bungs fit nice and snugly, so helped with the job… but you still have to be quick and know what you are doing to avoid a flood! A little bit pricey for two bits of moulded synthetic rubber.

Excellent thank you 👍

Handy item, time saver, to change radiator or valves, no need to drain down full system,just rad your working at.

Wow,what can one say you stuff it in the hole and nothing comes out! If you stuff the other end over a pipe the mazing happens again NOTHING COMES OUT

I was pleasantly surprised by the quality of these, purchased them to isolate my F&E tank so I could replace a seized 3 port valve without having to drain my hot water cylinder down, worked a treat and held while I did the job, these will last for years and would stand up to frequent professional use

Very useful
