Neish Tools Dry Pressure Test Kit 0-4 bar

Connected this to the central heating system, pressurised with a portable air pump and it's pressure gauge reading was almost identical to that of the pump. The reading on the boiler gauge was slightly different and I'm guessing that's because the boiler was some distance away. The pressure slowly dropped and it turned out to be an old solder joint under the floor, which will be tiled over. So this did its job and saved a lot of headaches later on. Great product at a great price!

No plumber (/DIYer) should be without one. So many expensive mistakes can be avoided by using one.

Invaluable bit of kit. Saves leaks while filling pipework without soaking anything .

It leaks from the valve, don't waste your time
