Running new MDPE pipe to water main

[UKPITA]

Hi All

Looking for quick bit of advice.... been asked to replace old galvanised pipe work with MDPE due to corrosion...

What size pipe would you recommend 20mm or 25mm?? as this will join onto some existing 1/2" Black alkathene BS1972 pipework that feeds into the house...

Do not sat size taking out or length but as said go for thr 25mm as not much differance cost wise and leave options open for future system installs 🙂

Thanks for replies.... I think 25mm it is then.....

As mentioned in initial post I will be joining this back up to the existing 1/2" alkathene, inside the property will be direct feed for the cold and gravity feed cylinder for the hot.... (Already existing!)

Great help, much appreciated!!
