Home Master TMHP HydroPerfection Reverse Osmosis Review

Home Master TMHP HydroPerfection Undersink Reverse Osmosis Water Filter System

Overview of the Home Master TMHP HydroPerfection

Our #2 pick for most people (and #1 if you have a well or natural water source) is the Home Master TMHP HydroPerfection Reverse Osmosis system. 

If you don’t to want waste time comparing options and just want to be sure you are covered in every water source situation, then the Home Master TMHP HydroPerfection is the best reverse osmosis system for you.  It comes complete with every major feature and every possible filter – 9 stages in all!

The Home Master TMHP includes a permeate pump, which increases the output of the system to 75 gallons per day and reduces the amount of waste water needed to flush the membrane to just 1 gallon for every gallon of purified water produced.

It has a remineralization filter that adds safe minerals back into the water and raises the pH to be more alkaline.  This creates a fresher tasting mineral water.

The system also has a UV (ultraviolet) light that will kill 99.8% of microorganisms that may contaminate your water.  Municipal water sources are usually low in microorganisms but well water and other natural sources can have higher levels.  UV filters are highly recommended in situations with natural water sources.  Keep in mind that a UV filter requires a standard 110V power outlet.

The TMHP is rated for about 75 gallons of purified water per day and in addition to an upgraded faucet, the system now uses a larger 3/8” diameter tubing. This larger bore tubing helps increase the flow rates and the speed at which the purified water reaches the faucet.

Filtration System Design

The Home Master TMHP HydroPerfection system has a modular filter design that makes changing filter elements easier. Each of the filters is contained in its own housing, which is changed out with the filter. This solves a problem that can occur in systems that keep the same housing since some of the debris that had been removed by the filter can remain in the housing. This reduces the life of the filter and could damage the housing.

There is also no need for any tools when replacing the filters – you simply pull the old filter out and push the new filter in.  Filter change instructions, which should be carried out at least annually, can be found on the Home Master web site.

Water Efficiency

The Home Master TMHP HydroPerfection is one of the most efficient systems you can find as it creates only about 1 gallon of waste water for every gallon of pure water produced (1:1 ratio). This amount of water waste can vary depending on the pressure of the water entering the system.  The higher the input pressure, the less water wasted. The waste is created because RO systems use pre-filtered water to clean the filter membranes.  However, the permeate pump included with this system increases the pressure and helps to both reduce waste and increase efficiency.

Ease of Installation

The Home Master TMHP HydroPerfection system is designed to be installed by anyone with rudimentary DIY skills.  A professional plumber is not needed to install this kit.

The only potentially difficult part of the whole installation is drilling a hole in the sink top for the pure water faucet. This may not be necessary if a hole already exists for a hand sprayer, soap dispenser, or is available with a blank cover.

The full installation instructions and owner’s manual (found here) covers how to connect the feed pipes and drainage pipes over 7 pages and Home Master has made a series of 6 videos that show an installation.  For many, it is easier to watch these videos before attempting the installation.  It is well worth spending the time to watch the videos, as they clarify some the of instructions in the manual.

The installation of the permeate pump is not included in the video instructions, so check out section 3a of the instruction manual for details.

Take note of the need to have enough room to remove the unit for annual maintenance.

The videos do not include instructions for the UV unit, so see section 8 of the instruction manual for details.  Also keep in mind that the UV unit requires a 110V outlet available under the sink, which you are likely to have if you already have a dishwasher or garbage disposal.
