Check Valve
6 Answers
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
