I needed a good "whole house water filtration system" for my 2003 Alfa SeeYa 40ft RV. Couldn't find one that fit my needs so I built mine from parts ordered here from Revain. I saved 50% building my own system and I think it's the best on the RV market. The key here is full flow, no pressure drop, 100% full filtration and ease of use with full portability. Shopping list: a. (1) MMDetailz RV Water Pressure REG. & caliber A01-1117VP, b. (2) Pentek 150237 #10 Big Blue 4.5" x 10" filter housing with 1" in/out. My pre-filter stage 1: (1) Aquacrest AQU-AP810 4.5" x 10" i .My post-filter stage 2: (1) Ronaqua B01MOD19G2 Big Blue Carbon Block 4.5" x 10" filter, e. (1) 1" brass closed nipple to connect two Big Blue water bodies together, f.(2 ) 1ft to 3/4" hose adapters for inlet and outlet ports connected through Big Blues, D.(2) 3/4" MPT x 3/4" MHT on each end, H.(1) 3/4" " x 3/4" FHT swivel. Easy to install and I now have a GREAT filtration system for my RV. My wife is happy and so is I!"
