TSM-400 Whole House Reverse Osmosis Purification Package

Our compact 1-2 people reverse osmosis system & whole house water treatment package.

The most comprehensive RainDance 400gpd whole house well water reverse osmosis with pretreatment package on the market - Compare!  
Our ultra-friendly TSM-RO 400gpd Packages are highly desired for brackish salty well water or city treated water to reduce the levels of total dissolved solids and suspended matter. The principal uses of our whole house reverse osmosis systems are for the treatment of impurities such as chromium-6, nitrate, sulfate, sodium, chlorides, arsenic, copper, lead, fluoride, aluminum, metals, chemical contaminants, uranium, radium, gross alpha, beta particles and total dissolved solids up to 2500ppm.

Did You Know?: The # 1 reason for most whole house reverse osmosis system failures is inadequate or no pretreatment - proper pretreatment is vital to the longevity of your ro equipment! Without pretreatment your RO membrane and other expensive components can degrade in weeks if not days. Because water chemistry can vary from water source to water source the specialists at RainDance Water Systems have included our custom RainDancePRO pretreatment system to all of our 400gpd through 1500gpd whole house ro packages. Now, have peace-of-mind knowing that your new whole house reverse osmosis equipment is being protected by the very best pretreatment RainDance has to offer! The RainDancePRO is a custom water softener designed for both city and well water sources. The RainDancePRO will protect the ro system from iron, manganese, hydrogen sulfide gas and soften hard water all of which will degrade the ro system if not pretreated. The RainDancePRO is not a standard water softener - The RainDancePRO is equipped with a pretreatment lock-out switch that works in conjunction with the RO system. When the RainDancePRO is ready to regenerate and clean itself it will automatically turn off the ro system - when the RainDancePRO is done regenerating it will then turn the ro back on. Why is this important? Standard water softeners allow untreated water to pass through the ro system while they are regenerating - this can lead to premature membrane fouling and untreated water in your storage tank.

Compare our consumer friendly Compact Whole House RO Package to any similar whole house purification package on the market today! You'll find that no system can stand up to our TSM-400 Whole House RO Package, and on top of our superior purification package our customer service and technical support is unmatched. Find out what makes this package unbeatable below.

Sizing your Whole House RO System: Keep in mind that an RO system produces a certain amount of purified water within a 24 hour period, so it's important not to undersize the system. You should size your whole house RO by cutting it's rated gallon per day capacity in half for household production. For example, our TSM-400 Whole House RO system can produce 400 gallons within 24 hours, or approximately 200 gallons every 12 hours, so this system should be considered when no more than 200 gallons is used in home per day.

NEW! Best-In-Class Easy Automatic RO Control Panel now included with the TSM-400 Whole House RO Package. Our integrated electronic controller offers automated control of several system functions and helps prolong the life of the RO motor and membrane, providing long-term and reliable operation. Built with superior engineering, this control panel eliminates confusing switches and lack of feedback provided by other generic RO systems.

The Automatic RO Control Panel allows the home owner to easily monitor the performance of their system by using easy-to-read light up indicators for common RO functions. Certain features such as the System Flushing and Low Pressure provide added protection by automatically cleaning the RO membrane and shutting the RO system off in events of low water pressure. Low water pressure can cause an RO system to cycle on and off which can burn out the motor and increase noise level. Other features like the RO Pump and Tank Full keep you informed when the system is running and you have a full tank of purified water. With automated control it has never been easier to operate a whole house RO system!

SIMPLE OPERATION: Quick Guide On How Our Whole House RO Works: pressurized water from your city treated or well water source enters the RainDancePRO water softener which protects the ro system from hard water, iron, rust, and hydrogen sulfide gas the treated water then enters the attached dual prefilter cartridge system to remove sediment, chlorine, organic chemicals, herbicides, insecticides, and pesticides. Then this pre-filtered water enters the Whole House RO water purification system. This Purified RO water then enters the pH neutralizer / remineralizer then begins to fill the near-by storage tank. The RO water will continue to fill the storage tank until the included tank float switch closes and shuts the entire system off.  When there is a demand for water the re-pressure delivery pump is activated and draws RO water from the storage tank to your taps. If enough water is used to the point where the float switch is reopened, the RO system is automatically reactivated and begins to replace the RO water in the tank that has been depleted.

 What does the Electronic RO Control Panel do and why is it important?

A: The Electronic Control Panel provides hands-free and worry-free operation of several functions of the whole house RO system. The basic RO functions include the "feed pressure switch" and "tank float switch" which regulates the system operating. The "feed pressure switch" ensures that your incoming water pressure is high enough for the RO system to operate (typically above 25psi). The "tank float switch" tells the RO system to shut down or start up based on your storage tank's water level. These basic functions are built into the RO control panel for smarter regulation and eliminates external switches.

A bonus feature included in our Electronic RO Control Panel is automatic membrane flushing. Most whole house/light commercial RO systems on the market today do not provide a membrane flush, which helps extend the life of the membrane by removing the concentrate brine (extremely salty water expelled by the membrane) sitting on the surface. Our whole house and light commercial RO systems included a manual membrane flush that allowed the user to flush the membrane as they wanted to. With this Electronic RO Control Panel, our customers no longer need to worry about remembering to flush the membrane constantly; this control panel automatically activates a membrane flush both at start up and shut down, ensuring longevity of your RO membrane.

The most important feature on this control panel, however, is the low pressure shutdown. Both public city water users and private well water users can suffer from periods of low pressure which can have a great negative affect on any RO system. If you experience a period of low pressure, a standard RO system would cycle on and off until the pressure is regulated. This can cause wear and irreversible damage to the RO pump motor and external feed pressure switch, resulting in costly and labor-intensive repair. Our RO control panel prevents this from happening by automatically shutting down the RO system if your feed pressure remains low for an extended period of time.

An optional feature on our RO control panel is pretreatment lockout. When pretreatment is needed to protect the RO system, a backwashing filter or water softener is used. When these pretreatment systems shut down to clean themselves, they allow unfiltered water to pass by the system and get into the RO if it's running at this time. To prevent possible exposure to unfiltered water a pretreatment lockout switch can be used to shut down the RO system when the water softener or filter is regenerating. Once the pretreatment system is finished regenerating, the switch will reactivate the RO system again. Both the RO system and the pretreatment system will need to be specially fitted with pretreatment lockout. This option is included free of charge when you add any of our pretreatment water softeners, iron filters, or backwashing systems to your whole house RO system!

Each function of the control panel is displayed with varying indicator lights to let you know how the system is running. You won't have to wait until it's too late and there is no water when you turn on a tap. Our Electronic RO Control Panel prevents potential RO malfunctions from happening and allows you to catch the culprit in time, before it has a chance to harm your system. This fully automated control is a must-have for any home owner that wants a hassle-free solution to many water problems.
