Blue water main connector to 1/2” thread a reasonably well priced to connect blue plastic to copper pipe
Allotment water supply: used this to connect to the float valve on a tank, replacing copper fittings.
Great fitting that works well & doesn't leak. Would recommend.
Top quality good quality for the money and always go to Toolstation
Great for allotment water troughs, work well - winter will tell how robust they are. There is a problem in that we ordered 10 but only 9 were delivered. Unable to talk to Toolstation staff as telephones are not being answered, and no response to email as yet. I cannot currently recommend the delivery service option.
Bought these for refurbishing horse troughs . Everything OK so far, but a season of abuse to come before we will know for sure :)
