Matt,

I have had some limited experience with the Headhunter toilet and I might be able to help a little.

First, the flush valve which controlls the length of the flush is easily serviced. I hope yours is accessible. If it is open it up and insure there is no foreign material in it, especially any that would impede water flow through a very small hole in the diaphragm. That small hole is there to allow water to flow from one side of the diaphragm to the other to stop the flush. If the hole is plugged or partially blocked the toilet will run for a long time.

On my toilet installation there was a ball valve on the side / rear of the toilet that supplements the flush valve and the amount it is open regulates the volume of water that remains in the bowl after the flush.

The flush is initiated with the button on the side of the toilet and that trips a solenoid that moves the diaphragm to initiate the flush. You want to make sure before you reassemble the flush valve that the solenoid is not hanging up preventing the diaphragm from re-seating.

Matt,

I just replaced the flush button and timer on mine, that cured the problem of long flushes for me. I also replaced the rubber diaphram earlier as Jon pointed out and that didn’t solve my problem, but I would try that first before buying the button and timer, they’re pricy. Here’s a couple pics for you.

Like Jon said, there is a very tiny hole in the center that gets plugged and can cause long flush.

I experienced the same problem and it required the same fix….replacement of the flush valve.

As a temporary fix, until I could get the parts and make the permanent repair, I replaced the combination flush button/timer assembly with a simple momentary switch. With the momentary switch in place, the toilet would flush as long as the switch was depressed. It actually was somewhat of an improvement of the original installation as you could control the length of flush to suit the purpose.

I ended up replacing both the flush valve and the button switch. The new switch from Headhunter, although pricey, was an improved version of the original I removed.

Hopefully your flush valve will be easier to access than mine was, which required pulling out the refrigerator. In a Liberty, that’s a project….

Thanks Guys,

I found the solenoid, it’s located behind the Glendenning cable master in the plumbing bay. I was also tempted to put a momentary switch in to solve the problem temporarily, Furthermore I dry camp quite a lot and was concerned this toilet used this much water on a regular basis. What is the logic on the timer, can anyone explain the four wires coming in and out of it; what’s the polarity and if I were to wire a momentary switch what should I keep in mind. Thanks!

I’ve also replaced my switch and timer with a push/hold on switch and have found the results satisfactory.

I had same problem with mine, I replaced the timer, and now works fine. I keep mine adjusted on the shortest flush, due to dry camping mostly.

Matt,

You have 4 wires, two go to the button and the other two are 12v + and -. The timer is adjustable, have you tried that yet?

While we’re on this subject, I’d like to hear some opinions on the various brands.

What do you think of the Microphor?

What about the Tecma Silence Plus?

I’ve used the Headhunter for a few years and found it to be quite satisfactory. The water usage is easily managed using the techniques described above.

[tom]

Ok, I can actually offer something here. We have had a Microphor toilet for 9 plus years and we really do like, once we figured it out! There is a small O ring that needs to be lubricated yearly or it will fail and leak water. Found that out the hard way! But now it works great! The one thing is that if it is not positioned directly over the black tank, it will not work properly as this toilet is a gravity fed toilet!

I like the Headhunter because the system is simple. The downside is to properly flush you need a large sudden flow of water at a reasonable pressure so to make it work on my anemic 1.4 GPM back up pump I am in the process of installing an accumulator tank directly in line with the inflow water line to the flush valve.

I’m optimistic it will work even if JDUB uses the toilet.

This is my latest addition in order to keep the Mach 5 from cycling because of the RO system. Really big difference now, I can use a bunch of water before the pump cuts in. I told Jon my hope is this will do the trick at campgrounds with high water pressure and run the Royale Flush without the pump. He says I’m smoking something, so we will see. Many of you Liberty guys already have this accumulator tank hidden in your galley, but the early ones like mine didn’t have it.

Gary – I’m betting that with my removal of the restrictor and 45 psi water regulator and replacing with a 60 psi regulator I’ll be able to flush with city water and no pump as long as the city pressure is high.

I did notice the shinny brass …. nice clean installation

I think Tom removed a pressure limiting device to allow good flow from city water, and that is good. My concern is unless the accumulator is connected to the system in such a way as to give a straight shot of water flow into the Headhunter toilet flush valve he may not have a fully functioning toilet on city water.

I am adding an accumulator tank to my coach in the hopes I can get the pressure and volume of water needed to flush my Headhunter toilet, but I am jumping through some hoops to get a flow direct into the flush valve. That will allow everything to work when using my 1.4 GPM back up pump.

Thanks to Tom I am also installing my accumulator tank under the bathroom sink. For months I have been trying to figure out how to get it into the already crowded water bay.

Jon and Tom if u spent more time driving and staying in coach u would not have to badger each other about updates Just kidding laugh out loud just left Calgary and will be home in 3 hours 950 miles in 16 hours what a nice drive. I have had tecma for 10 years and u can adjust water use and it’s bomb proof never a problem I think micro toilet is junk compared to tecma mine is rear discharge By the way my aux comps never comes on any more once I got rid of the micro air toilet

By the way Tom fixed holding tank smell when driving down road cracked vent pipe at roof put new vent on also no smell now with drivers window open all day when driving
