Residential reverse osmosis system

A reverse osmosis (RO) system comprising:

• a manifold that receives feedwater for the reverse osmosis system and delivers permeate and concentrate from the reverse osmosis system;
• a pre-filter housing that includes a pre-filter, wherein the pre-filter housing receives feedwater from the manifold and delivers pre-filtered water to the manifold;
• a first housing that includes a first membrane element, wherein the first housing receives pre-filtered water from the manifold and delivers permeate and concentrate to the manifold;
• a second housing that includes a second membrane element, wherein the second housing receives pre-filtered water from the manifold and delivers permeate and concentrate to the manifold;
• wherein the pre-filter housing includes a first end attached to the manifold such that feed water flows into the pre-filter housing through the first end of the pre-filter housing and pre-filtered water flows from the pre-filter housing through the first end of the pre-filter housing;
• wherein the manifold supports the first ends of the pre-filter housing, the first housing and the second housing;
• and
• further comprising a leg that supports opposing second ends of the pre-filter housing, the first housing and the second housing.
