Ro tank hookup

Without a tank to provide constant back pressure for the pump's pressure switch, a phenomenon called "pump chatter" sometimes occurs.

If the pressure drops slightly, the pump has to turn on briefly to renew the pressure when no demand for water has been made. A demand pump, while not always essential, improves the performance of virtually any demand pump installation. Demand pumps are versatile tools that can also be used to send water to a car wash location, a fish pond, or a hot tub. They are sometimes used to move water from a non-pressurized distiller tank to a sink-mounted spigot.
They work anywhere a pump is needed to move water to a point of use. The illustration below shows a demand pump installation on an undersink reverse osmosis unit designed to send pressurized water to a remote refrigerator or icemaker. This is a good design, but there are many other placement options. More about Demand Pumps.

The Pure Water Gazette features daily updates on news from the world of water. You are invited to visit. The pressure tank at right is the RO unit's regular storage tank. The tank at left is an additional "pump tank" added to smooth out the pump's operation and to provide extra storage. Water in the second tank is available for both the kitchen ledge faucet and the refrigerator. A copper tubing cutter is the ideal tool for making this cut although a hack saw can be used.
If a cut is made, a new compression ring not supplied will need to be installed to make a new water tight connection with the riser tube and the angle stop shut-off valve. The drain saddle valve should always be installed before above the p-trap and on a vertical or horizontal drain.

Do not install the drain saddle near a garbage disposal to avoid clogging the drain line with debris. For convenience on under sink installations it may be advisable to complete under sink tubing connections at this time. Install RO membrane O-ring end first, carbon prefilter s and sediment pre filter in vertical mounted housings. Be sure RO Membrane is pushed into Membrane housing as far as it will go. It is recommended that filters and membranes be handled with clean or gloved hands.
The RO unit is normally mounted to the right or left sink cabinet sidewall, depending on where supply tank is to be located. Generally the unit is installed at the front of the cabinet and the tank at the rear. To mount the unit, elevate it at least 2" off the floor, level it and mark the location of mounting holes needed. Drill hole for mounting screws and install screws allowing the mounting bracket slots to slip over them.

If the cabinet sidewalls are not solid, unit may sit on the floor with screws used just to keep it against the cabinet in a vertical position. Pre-filling the storage tank is recommended so there is sufficient pressure to check for leaks and water to flush the carbon post filter. To do this connect the feed line that will serve the RO unit directly to the bladder tank. Allow the water to fill the bladder until it stops. Close to tank valve, shut off the feed pressure, release the tube from the reducer and remove the reducer from the tank valve.
With all components in place, complete final tubing connections with these guidelines: To complete this operation, connect a T with a shut off valve into the faucet tubing and route tubing to the refrigerator. Hooking up to existing copper tubing is not recommended due to possible corrosion Turn off icemaker inside freezer prior to turning off the existing tap water supply line to the refrigerator.
Turn on the icemaker after the RO system has been drained several times and the tank has a full supply of water. Icemaker lines are often run in the rafters of unfinished basements or finished basements with drop ceilings and then up to the fridge. In cases where a basement or cabinets connecting sink and fridge are not available, icemaker connections cannot be made.
Before any service is performed on the RO system, turn off icemaker valve and icemaker unit. Turn back on only after RO system has been sanitized and flushed out. Each year the filters in the system should be replaced. Usually the membrane can be replaced every other year, but the pre-filters and post-filter should be changed annually and in some cases more often. When installing a new membrane be sure to push the membrane into the housing as far as it will go.
Each time the filters are replaced it is recommended that the system be sanitized. After all filters are removed from the system, housings have been cleaned, tank is empty, and faucet is open RO Systems are highly sensitive to pressure and temperature. RO Membranes always perform better under higher pressures.

They produce more water, faster, and of better quality with high pressure. The vast majority of problems with RO Systems are a result of low pressure. The effects of low pressure include water constantly running to the drain, slow water production and low water volume available in storage tank. In these cases where low pressure exists, a booster pump will be required.

On the following page is a table showing RO Membrane performance over a range of temperatures and pressures. Membranes are tested at 65 psi of pressure and temperature of 77 degrees. For each incremental change in either variable, membrane performance changes accordingly. Higher pressures increase production and vice versa. To troubleshoot a poor performing RO System an accurate measure of the pressure and temperature of water will be required. This will require a pressure gauge to determine exactly what the water pressure is that is feeding the membrane.
