Here are some of the products I use and recommend…

Can be installed in every orientation. Safe for drinking water. Comes with mounting kit

Optional but recommended. Extends life of pump and makes water run nicely with controlled flow

For connecting the semi-flexible piping. I recommend using metal jubilee clips in addition, for extra security

Food grade piping safe for drinking water. This is semi-rigid flexible used for all water installation in the van

Essential for making your pipe installation look nice and to keep it out of the way
