Headhunter pump problems - folivier - 03-26-2013
The headhunter pumps runs up to 58 psi then runs for a minute or so then cycles off and the pressure drops to 30 psi and immediately starts running again. It does this repeatedly until it shuts off due to overheating.
The 12 volt pump runs ok, pumps to 35 psi and cycles on and off properly.
The headhunter pump was running ok until I filled the water tank through the tank fill at top of tank. It started cycling right after.
Any suggestions?

I had problems with mine doing the same thing, but it was a combination of air in the lines, and the "city water" valve was open..

Try using water from every device served by the pump in an effort to let any air trapped anywhere a chance to get out. You are describing exactly what a headhunter will do with any air in the system. Good luck!

prime the pump or you can destroy the impeller if you continue to run with clicking noise inside pump.
RE: Headhunter pump problems - folivier - 03-26-2013
The pump is primed and full of water. Just ran each faucet and so far it seems ok. Wonder if I have somewhere in the water systems that is allowing air in the system? Don't see any leaks anywhere.
Wait just remembered that the fitting on top of the headhunter does have a slight leak. Could this cause the problem?
RE: Headhunter pump problems - encantotom - 03-26-2013
forest, fix that fitting soon. what makes these headhunter pumps go bad is that the cover on the top that is over the circuit board will leak and short circuit the board if there is constant wetness. everyone i have seen or heard of going bad was for that.
does your pump cycle when the icemaker fills up with ice? i have heard from jimmy that if you dont have a bladder tank that small uses of water might cause the pump to cycle. i do not have a bladder tank and it hasnt been an issue.

We just replaced a headhunter that was cycling. It would go to 65, shut down pressure dropped immediately until shutdown.
Turned out the reverse osmosis filters connected to the ice maker was causing the problem. It took some time to purge the air out after. I checked Monday and it has set a week now w no pressure drop. Added a 3gal accumulator to handle the ice maker and inline taste filters replaced the reverse osmosis filters.
We also had a electric city water/fill valve that was sticking. We took it apart n cleaned.
There is some good info on the headhunter web site That may help. But you have something leaking back into the system or air leak. If it was working before the fill good chance whatever you moved switched or inline check valve moved is where to start.

We're going to attack Forest's water pump issue today, but I have a few questions. It does act like there is an air leak. My question is when we shut off the Headhunter and turn on the 12V water pump, why does it not cycle in a similar manner? Why does the pressure gauge stay solidly at 30 psi? Does Headhunter have tech support available?
Thanks in advance.......................
RE: Headhunter pump problems - Ozarkguy - 03-27-2013
Steve you can call them and they'll help.. There is also a couple of video's on this site that will help some. Plus some warnings in the installation manual. http://www.headhunterinc.com/Products/WaterPressure/WaterPumps/mach5.html the manual is in the documents section of this site, provided by Tom.
Also look for a check valve that may be isolating the 12v pump in the system. it could have something in it.. Isolate the Mach 5 and see what you have if all else fails..
RE: Headhunter pump problems - RussWhite - 03-27-2013
Steve,
If the symptoms are still pump cycling I think tech support will tell you what they told me years ago and that is that there is air in the pressurized portion of the water system. In my case I had let the pressure go to zero due to changing a water filter. Once I purged all the air from the system the pump performed perfectly. It is programmed to run for some number of seconds ( don't have book handy ) even after demand has been met, and then shutdown until there is a new water demand. I have never had any problem with small demands like the ice maker that someone mentioned. Air, of course, can only get into the system once everything is closed up on the section side of the pump. Sunction side leaks can be hard to find. Russ
