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
