Crappy toilets

OK, pun intended. For those that have the Dometic masterflush 7600 series toilet, is there a way to adjust the water flow coming out of the rim. The streams of water coming out when I flush only covers maybe 50% of the bowl and by the end of the day it smells like a urinal. I have it set to the normal flush mode but I have to pretty much clean the toilet every day. My water pressure is pretty good, so it’s not low water pressure.

I looked, but didn't find anything on flow adjustment...may have missed it. In case you do not have the manual...

If the adjustment isn't included here, maybe call Dometric (330-439-5550)to see if adjusting is even possible.

I called Dometic and they said the water valve may need to be replaced. They said since it’s still under warranty then I should take it into a dealer. The funny thing is that both of my toilets do the same thing, doesn’t rinse the whole bowl when flushed. My water pressure is 54 psi and I use a portable water softener to help keep water lines clean.

The chances of both water valves being faulty on a new rig are next to none IMO.

Here's a couple of ideas that may or may not work...
After looking at the pic's in the prior attached manual above, when you press down on the flush peddle—that plastic linkage right there—is there a way where you can detach it, rotate that arm a notch or two then hook it back up so now the linkage opens the valve more, thereby allowing more water in? Or maybe adjust the peddle up a little so when you press it down, it would open the valve a little more?

One of our toilet water valves starting leaking about 3 weeks ago and I had to replace it. It's tight back there but got it done. About an hour and a $35 new water valve.

I think you need to check the flow rate ahead of, and after the water softener, or just remove the softener and see what happens.. I

Trust me, if I start to tinker around on the toilet I will make it worse. I did increase my water pressure to 60 psi and it helped some. Not sure if I should try to increase it more. I haven’t hooked the water pressure gauge after the water softener yet to see what the psi would be, will try to get to to that today.

When you hook the pressure gauge up after the softener, you'll see the same pressure as ahead of the softener, until you turn a good heavy flow of water. Then you'll get an idea of how much the softener may be blocking the water flow.

Just depress the pedal to where you have water flow without opening the ball valve and fill your toilet up as a residential would. They you have taken care of the residual urine and add water to the black tank to make for much better dumping. I also use the shower head to add hot water to the bowl, a little bit of Pine-Sol, a quick brush every 7-10 days and no problems at all.

Can you add a hand sprayer? That would make the use of water more effective.

Please let us know how you resolved this issue so we all can learn.

Good luck my friend.
