Permeate pump equipped systems will “click” and “whoosh.” Sounds should stop once the reserve tank is full.
Sounds should last for approximately 1 hour per gallon of water used. Hissing or flowing sounds from Home Master™ RO are normal during the water purification process.If water center works, but icemaker does not, then defrost the freezer as the line in may have frozen. Make sure refrigerator water center and/or icemaker are turned ON, and refrigerator is plugged in. No water or ice from refrigerator water center Make sure line from Home Master™ RO to refrigerator has pressure.Eliminate possible blockage points by disconnecting each system component and checking for pressure. Make sure all valves are set to the ON position. No water from Home Master™ RO System Double check to make sure there is “no water” and not ”slow flow or trickle”.For plastic fittings only make sure the plastic tubing has an insert in the tube end, and a feral (o-ring which compresses the tubing around the insert) in the plastic female fitting. Under tightening can result in leaks, over tightening can crush the tubing and result in a water blockage. Leaks from plastic fittings Plastic fittings should be firmly finger tightened.Most push-pull fittings take about a ½” of tubing inserted into them. Push tubing all the way in, then pull back gently, to check fit. Re-insert the tubing into the push-pull fitting. Scratched, gouged, damaged, or oblong tubing end WILL leak. Make sure the tubing is cut is straight, the edge is completely smooth, and the tube is rounded. Tubing cannot be pulled out without depressing the fitting ring, and relieving system pressure. Then pull out tubing while the ring is still depressed. Leaks from quick connect, push-pull fittings Disconnect fitting by pushing in the tubing with one hand and depressing the ring on the fitting with the other hand.Over tightening can crush the tubing insert and cause a water blockage. Tape should be wound 5-7 times around male thread. Leaks from metal fittings Unscrew fittings and re-tape male fitting.Push-pull fittings are nearly impossible to remove when under pressure. IMPORTANT NOTE: Before performing service on the Home Master™ RO at any time, and for any reason: first switch to the OFF position all under-sink water valves, except for the RO sink spigot which you should switch ON to relieve system pressure and drain away excess water from the lines.
