As a temporary supply I connected some 20mm MDPE pipe to my 3/8” Alkathene water main using a Plasson connector and adapter. I’d now like to run 25mm MDPE from the 3/8” main to the house, the only adapter I can find to do that is this one: https://www.plumbnation.co.uk/site/talbot-grippa-universal-adaptors/?gclid=EAIaIQobChMI4tTch_D36AIVpoBQBh1IFwn3EAQYAyABEgK1K_D_BwE I’ve never heard of them before. Are they any good? Are there better options? Ta in advance.
PeterW Posted April 20, 2020 Posted April 20, 2020 3/8” sounds really small - is that the internal diameter ..? If the 3/8” is already connected I wouldn’t disturb it but just cut the 20mm and get a 20-25mm connnector - short restriction won’t harm it. 1
