20 Most Recent Mountain Plumbing AG600S Air Gap for Reverse Osmosis Systems Questions & Answers


One thing you can do that should help you without to much expense is to in stall a dual soft seated check valve directly upstream of your air gap. This should help quiet it down.
One other thing you can try if your R.O. system is a small under counter unit that has the r.o. membrane and filters mounted in a moveable unit is to turn your r.o. faucet on and tilt the filter unit forward at about a 45 degree angle. Do this at least ten times and see if that helps with the noise. I have seen several smaller units that have a automatic shut off valve that will chatter or cause other problems if this is not done. Hope this helps you. Thanks

there is a cloged line between the air gap and the disposal (if you have one) or the drain under the sink.
you will need to remove the pipe and flush out with water. this is usually a rubber hose. most of the time, the clog is at the disposal where the rubber hose connects.
you should be able to see the clog once you remove the rubber hose. clean this out ( I use popsickle sticks) once cleaned out, reinstall the hose and try your dishwasher.

http://www.ag.ndsu.edu/h2oqual/watsys/ae1047w.htm Treatment systems for household water supplies gives a great description for reverse osmosis systems. I am not familiar with the Maruyama system since I live in the states. After reading the above article you might want to test your water. Your system may be operating properly? To me it soulds like you have a water softner and flushed the salt out, and now you have the proper pellets? If your water is not very hard you shouldn't use too much salt. Building supply stores sell cheap water test kits. Try that, and if your water tests ok, and doesn't smell, and lathers up with soap sounds like everthing is working ok. Hope I helped

Unfortunately this sounds like more than a blockage. If this was a blockage water would not drain, maybe fill in sink or dishwasher etc. If water is coming from walls probably means it is leaking from drain pipe in the wall. Which would mean opening wall to find leak.

If you are referring to limiting the temperature of the hot water to prevent scalding, then a tempering or mixing valve can be plumbed in between the cold and hot water lines. This type of valve adds cold water to the hot water and it is adjustable.

(1.5ft)^2 * Pi * 30 ft * 62.4 lbs/cu-ft = 13232.4 pounds plus the weight of the pipe which will vary depending on the material of the pipe.

You can find the weight of the pipe if you know the brand and material as most manufacturers will list the weight per foot in their catalog.
30 feet has about 11.94 cubic feet of whatever material the pipe is made of.

The pressure produced by a pump depends on it's capacity and efficiency, the power of the motor driving the pump and the resistance of the pipework.
Without the resistance provided by the usual pipework the pump produces negligible pressure and just merely moves the liquid.

Given the motor power and pump capacity/efficiency are fixed values, the only reason the pressure would increase is the resistance provided by the pipework has increased.

If it isn't too late, I have a single crystal knob also. Couldn't find another when one of mine broke, so I bought two in the chrome finish. Let me know if you're interested in my (unbroken!) crystal knob.

I doubt the kitchen tap is actually turning itself on - or is it?
Perhaps fluctuations in water pressure are defeating the tap...

More details would have been helpful, such as mentioning the tap design (traditional or quarter turn type?) and when the hammering noise happens?

Hammering is often caused by a worn tap. When turned partly on the jumper can vibrate and cause the pressure in the pipe to fluctuate and magnify the noise, especially when there is a long run of pipe that is inadequately clipped to the wall...
