Keystone Hornet Toilet Water Pressure

[Remer Camper]

I have a 2013 keystone hornet 29 ft travel trailer. I'm having trouble with my toilet water hookup. I have a Sand point well which I'm pumping water into the trailer and I'm using an adjustable water pressure regulator going into the trailer. Even with my water pressure regulator set at 25 psi the water going to the toilet has too much pressure and the water is spurting out the nut that connects to the toilet. Obviously, I need to reduce the water pressure specifically going to the toilet. Any ideas on how I do this? Thank you!

Welcome to the forum

If it’s leaking from the nut where the supply line hooks up, I would turn off the water. Then remove the nut, inspect it for any cracks and install a new “swivel seal”.

Thank you very much. Yeah I have done that and replaced the seal and it still didn't do the trick. It looks to me like the water pressure is just too high as the toilet is about 2 or 3 ft away from where the water actually comes into the trailer. I think I need to somehow reduce the pressure specifically on the toilet line

What brand and model toilet do you have? Is it a Thetford or a Dometic and model number ??

Sorry, I am not sure.

If you're pressure is set to 25psi, accurately, you're not over pressuring the toilet. You have a faulty toilet part, faulty pressure gauge or both.

Actually, I believe you are correct. Hopefully I will not have to replace the whole toilet just because the fitting is bad

If your toilet is a Thetford, in that era Thetford toilets, the water connection flange is NOTORIOUS for splitting and leaking. Since we're just now coming out of winter, if it is a Dometic look at the inlet valve body. If you see a "small round bulge" on the valve body, it is internally damaged from freezing and needs to be replaced. On either type, if the water connector on the trailer PEX line is damaged or is the threads on the valve inlet are damaged, you'll increase your probability of a leak.

Here's both valves and the Dometic "freeze damage indicator bulge".

Also, bear in mind that 25 psi will be a very unsatisfactory pressure for your toilet. Your pressure and flow will not be strong enough to rinse the sides properly. Usual pressure is 45 to 55 pounds. .
