    Does the job

    Posted by Jonathan Clack on 8th Dec 2020

    Not so easy to come by. Had to search the internet to find brass 1/2 in thread extenders. Did the job adequately, nothing else to add really. However, Royal Mail delivery was shameful as it took 6 days to arrive following dispatch. Would have preferred DPD next day delivery if offered.

    Tap connection extender

    I was able to complete the fitment of a hidden shower coupling with this product. It was just what I required when other plumbing suppliers were unable to assist or offer advice. I will definitely be using plumbing4home again in the future and have already passed on the name to my family and friends.
