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

It’s a must for every plumber. Helps to block water outlets in the water tank.

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

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.

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

Excellent thank you 👍

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

Excellent product, made job much easier.fast delivery.

Arrived promptly, don't plan to use them for a few days yet but they look good and are substantial pieces of silicone/ rubber. Looks like they will do the job well. Let's hope.

👍👍
