Reverse Osmosis FAQs

Why is water leaking from the little hole below the handle of the faucet?

When water leaks from this hole (air gap hole) this means the drain line which runs from the base of the reverse osmosis faucet to the kitchen sink drain is clogged and needs to be cleaned.

Why is there a gurgling noise?

Some gurgling from your reverse osmosis is normal. If the noise is excessive you may need service. If this is a new installation it may take seven to tens days for all of the air to come out of the system then it will quiet down.

Why is my water cloudy when I first put it in a glass?

In most situations cloudy water is caused by air in the water, it is not harmful. Take a sample of the water in a clear container; if the bubbles rise to the top and form a white ring and the water is clear, this is air. If particles form and sink to the bottom call for service.

Why is the pressure from the refrigerator so much less than it used to be before the R/O was installed?

The reverse osmosis supplies approximately ½ as much pressure when compared to the incoming house pressure, therefore when the system is connected to the refrigerator there will be less pressure than if hooked up to house supply. Remove the refrigerator filter and replace it with the factory plug to help increase pressure.

Why do the tubes on the r/o system vibrate or bang around sometimes?

The most common cause of reverse osmosis tubes banging is backpressure caused from some other water source. In most cases if you have a swimming pool with auto filler the float is turning off and on rapidly causing the reverse osmosis lines to bang. It could also be your water conservation valve that is bad.

How do I use the TDS meter that came with my unit?

The meter that comes with the KR15 system measures total dissolved solids (TDS) in the water. Take readings of the tap water and the reverse osmosis water and follow the formula below to obtain the percentage of removal. If the percentage is above 70% the membrane is working ok.

R/O TDS reading divided by tap water TDS reading – 1 = % of removal

Why do I need to have my filters changed annually?

Filters in a reverse osmosis system should be changed annually to prevent the build up of foreign material that the filters trap.

When is it safe for me to turn my ice maker back on after a filter change?

After a filter change the ice maker can be turned back on eight hours after the second tank draining.

How much pressure should the storage tank have in it?

Before measuring the pressure in the tank it must be empty, after this is done the pressure in most cases should be set at 10-12psi.

How long should my membrane last?

Average membrane life is two to five years. The more a system is used the longer a membrane tends to last.

What should be done to the reverse osmosis when I’m going away on vacation?

The length of time you are gone is the determining factor. If you are going to be gone for more than 30 days the system will either need to be drained and allowed to refill, this is best if done every two weeks, or the membrane removed for cold storage in the refrigerator. If you leave for the summer it is best to shut the system down and remove and discard the filters, have the unit serviced when you return. if you are gone less than 30 days there is no need to do anything except shut the unit off if you wish to. Upon your return drain the tank and allow it to refill.
