Air in Tank when Marlo softener Rejuvenates

I replaced all the parts in the salt tank at the suggestion of the Marlo company but there is air in the cold water pipes after it rejuvenates and this did not correct the problem. However the water is soft after rejuvenation. Model No. EMP-30-KC . Marlo company told me they had no other parts available. The softener was installed in 1997 and the resin was replaced earlier this year. They said I might find help at Erie Controls but they could not give me information on contacting them.

I had a bad water valve which could not be turned off, in the copper pipe going to the softener input and I replaced it and after this the problem started.

Can anyone help me?
Thank You
Hal

What you might want to try is put the unit into a fill cycle and pull up on the safety float to stop the water from filling up the brine tank. If there is a leak in the brine line it will show and this is where the air is being drawn into your unit. If you do not have a safety, pinch the end of the brine line to stop the water flow.

Marlo water softener

Thank you for the reply. I had tried that at the suggestion of the Marlo Company.
I have since replaced the unit with a new Marlo Softener and watched it as it went through all the cycles and noticed that in every cycle water was being sent to the sewer. In the Brine cycle I noticed as the water went to the sewer there were many up to 2 inch long air bubbles. In my old unit i do not believe any water went to the sewer during the brine cycle, if that was necessary. Maybe that put air in the plumbing?
The unit is now replaced, so it no longer matters.

Thanks again for the reply

markandy on Sep 10, 2009

hi 1st timer.... I have a k3020 kinetico. the serial# on one of the 2 tanks says 321366. they are tan. Problem. I dont notice the top wheel moving at all. it seems to stay in one spot. also when I push down with a screwdriver to regen it, no matter what cycle its in water constantly flows from the tube going to my drain. also I took all the salt out of the big container/cleaned all the crap and just filled it about 4 inches above the base and turned on. the water level stays the same. nothing makes it raise or lower. A year ago gorden bros replaced the float, k-30 hy cup, control disk, repaired gearlog level 1, checked metering, cleaned valves......................................... now it has the above 3 problems... any help would be great...thanks

Culligan Gold Series not sucking brine at ALL

H

howdoesitwork on Aug 25, 2009

3 yr old Culligan Gold system hasn't been working for a couple months. Followed manual troubleshooting suggestions w/ no luck. Thought it was salt bridging, but after completely cleaning tank it didn't help. Finally, after reading posts, studying manuals and watching the softener go thru it's cycles, I think I've identified what's wrong. Just don't know WHY it's wrong. During the 62 minute brine rinse cycle (it's not called draw on my Culligan, but I believe it should be drawing the brine solution from the brine tank during this phase), the brine line puts a slow flow INTO the brine tank. Then, during the fast rinse cycle, it puts water in even faster. There is NO suction when I remove the brine line from the brine tank or from the control end - no suction at all on either end during this cycle. Shouldn't there be? So the brine can be drawn out of the tank? After emptying and refilling, we put 6" of water in brine tank (following manual) then added about 1/2 tank full of potassium. Now, 3 days later, the water level is about 3 inches OVER potassium. This should not be happening I know...the brine is not being pulled from the tank at all. Took apart as much as we could, following the diagrams on pgs 48 and 49 of: [URL="http://www.weareculligan.com/manuals/Gold%28RevA%2901017062.pdf"]http://www.weareculligan.com/manuals/Gold%28RevA%2901017062.pdf[/URL] We didn't find anything that looked out of the ordinary in the eductor assembly or brine line connectors. It was all very clean, no debris, rust, dirt of any kind visible. We ran a hose into the drain line and it's clear, so it's not that either. We do have a couple baseball sized O rings in a bag left by our Culligan dealer when unit was installed; think they go on the adapter assembly - the part that connects the resin/mineral tank to control box, but not sure. Does anyone have any suggestions? Culligan wants $144 to just take a look. If it's under warranty, the part won't cost anything, but we still have to pay for the $144...and of course, if it's not a warranty issue, the part too. Trying to avoid the expense right now so any help anyone can offer is very much appreciated. Very, very much appreciated!! Thanks for any help at all! Vicki
