Good morning all, I am part way through teh build of a log cabn and for water supply i was looking at connecting a caravan pump to hep20 pipes etc.  has anyone tried this and what would your advice be? as iam thinking that the variation in p ressure may not be "healthy for tehhep20 system.  additionally any pipe recommendations?

 

Thanks all

Seen plenty of motorhome builds including my own one using HEP20, a log cabin will just vibrate less at speed. With a maximum permanent operating pressure 12 bar at 20º, you're safe using a caravan pump with HEP20. Key is to install an accumulator and use a pressure sensing pump, that way you won't get pulsing and spluttering at the taps and the pump will behave better at sensing pressure drops.
