22mm Single Check Valve
What BAR PRESSURE?
I fitted this valve to my pumped hot water system as the pump was pulsing, only to be told later I needed a low pressure 0.5 bar valve as this one failed to let the hot water flow from the upstairs taps unless I turned on the down stairs tap first, please show the bar pressure for this type of valve.

None Return Valve
I needed to put a strainer on the end of a bilge pump hose. As the distance from the pump to the outflow was some 6ft and the pump did not have a none return valve incorparated in it I needed to stop the back flow. Placing this valve after the strainer has worked perfectly and I have found no resistance to impair the pumps capacity.

I used this product to stop the cold water from returning through the hot water supply in a bathroom with a mixer shower. The check valve lasted one week before it failed and I was called out urgently to rectify my installation, I have since used a double check valve and this seems to be doing the job.Not enough information supplied when buying the product i.e.pressure tolerance when connecting with mains supply.

Failed within one week of being installed in a central heating system to stop a syphon circuit through the return pipe. I now have to drain the system again and replace it. Seriously unimpressed and now put to a lot of extra work.
