Review: Perfect fit
Review: Following lots of YouTube tutorials we were recommended the John guest push and fit fittings. They are easy to use, we have had no leakage issues, just make sure your pipes have a nice clean cut. We also found the little round inserts to keep the piping in a circular shape handy. Great value for money and ease for newbies.
