Some Reverse Osmosis Questions

We have a new home under construction in the remote mountains of Colorado.
In our new home, our water source will be a well and our sewage will go into a septic system. Our current home has a reverse osmosis unit so we have some knowledge of those devices.

On Wednesday of this coming week the drywall contractor will start closing the walls and ceilings. We will probably want reverse osmosis drinking water to be available at the Kitchen sink and at both sinks in the Master Bath. The Kitchen is directly above the Mechanical Room. The Master Bath is above a storage room.

Our well has a very low regeneration rate. In order to collect and save some water during times that our usage is low, we have installed two three hundred-gallon storage tanks in the Mechanical Room. We are still clearing the silt out of the water from the drilling operation, so we have not yet tested the water. All of the well water in the general area tends to be
very hard. We will probably install a Water Softener and UV purifier.

The house will usually be occupied by just us but on some occasions, for a day or two, we may have as many as ten people in the house.

1. We think we would like to install your reverse osmosis unit high in the Mechanical Room and directly under the Kitchen sink. Would a Reverse Osmosis Filter with Permeate Pump create enough pressure in the storage tank to supply an acceptable flow of reverse osmosis water to both the Kitchen sink and the two sinks in the Master Bath?
The Master Bath is about thirty feet from the Mechanical Room. In both the Kitchen and Master Bath, the lift would be about eight feet.
2. If you think your unit will fit our application, please give us the specifications for the reverse osmosis water lines we should install Monday or Tuesday before our drywall is installed. In order to minimize the pressure loss on the long line to the Master Bath, we think might need to be
at least 3/8″ ID. Do you agree? Our plumber may want to use a 1/2″ Kitec line. Is that ok?
3. Our water supply is meager. We need to minimize the amount of water we waste. How efficient is such a unit? How much water does is throw away for each gallon it produces?
4. At both the Kitchen sink and the Master Bath sinks, we are installing nicely designed Delta faucets. Most of the reverse osmosis faucets we have seen are ugly. Do you offer or do you know of a firm that offers faucets that might look nice with our Delta faucets?

As is indicated in the prior paragraphs, since our drywall is going to be installed very soon, we need to take some action on our reverse osmosis installation immediately. We will very much appreciate quick answers to the above questions…

Thanks for contacting us.

Reverse Osmosis wastes a lot of water. TGI units are 3-4:1 / that means approximately 1 gallon pure water wastes about 3 or 4 gallons of water.

RO water needs plastic tubing. The standard is 1/4”. Cooper lines are no good for this, it will leak over time.

If the water is filtered, softened, and UV purified, it would be more-or-less safe for overall usage. RO technologies are used mainly for drinking water only.

A standard Booster Pump can be replaced by a Permeate Pump.

Faucets: According to our knowledge base, there’s no nicely designed faucet (as the Delta brand) for RO systems. There are faucets with color selection available, though. In any event, you may connect Reverse Osmosis water feed to a nicely designed special faucet.

Hope this helps.
