I wouldn't have bought another Wickes Aquatronic though!...You'll potentially have the same problem again somewhere down the line...
I use Gainsborough. Their design for a pressure relief device is a bit crude bit very effective. It is simply a small rubber ball inside a spur tube on the water outlet pipe (Where the hose attaches to)...If the pressure gets too great it simply 'fires' the rubber ball out of the tube and releases the water...The 'fix' is cheap...Just pop the ball back in to the tube! (providing you can find it!)
Triton are the same as the Wickes one...Once the PRD device has operated it's not cost effective to replace and
'chuck-it-away ' is the best option...Don't know about all the manufacturers though...
