Check Valve

[slid_away]

Hi All
I posted a few days ago regarding a garden tap that had stoped working and all indications pointed the the stop/isolation valve being faulty.
After some research I found out that the valve is a check valve with a stop tap on it to turn off during winter.
My question is , are these as simple as a normal isolation valve to replace or can they be fixed.
I'm not even sure if it's a singe or double check valve.
Your help as always is very much appreciated

A check valve is a specific type of valve ...
It has to meet a very strict criteria which ensures fluids are not able to be siphoned back into drinking water systems.
Standard isolation valves are similar in design and appearance to a check valve, but are not able to meet the strict criteria of a check valve which which can prevent backflow from occurring.

Thank you alavahalf..are these simple enough to replace myself. I'm a confident novice!

Very simple to fit .. just turn the water off at the mains and remove the two nuts on either side of the valve.
Wind a few turns of PTFE tape around each olive before you re-assemble ..

Take the tap off and throw it over into your neighbours garden. Fit a 15mm lever action ball valve in it's place. You will never ever have another problem.

Thanks Albert3...I'm not sure about that , he's a professional boxer!
But I'll definitely look at the ball valve
