Hi there, In an effort to improve the flow rate to our outside tap, we've sprung a leak . From the beginning, the flow rate from the outside tap has always been, so I replaced the tap, no improvement. The flow was still poor without the tap on. I checked for a blockage, there was none. I guessed the problem was under the sink from the tap fitting there, so the best thing was to replace it. I purchased a replacement self-cutting tap, took the old one off, attached the new pipe clamp, tap and hose. No need to make a new hole so I placed the new clamp over the existing hole. Unfortunately when I turned the water back on, the clamp is leaking. I have adjusted it 6/7 times but it keeps leaking. Any suggestions how I can stop it leaking? Thanks in advance!
