had an issue this weekend with my toilet. the valve would keep filling the bowl slowly. i flushed it a few times and this stopped but then i just had very low flow into the bowl when flushing. i ran to a local rv store and picked up a new valve and installed it. it fixed my problem. then i looked at the old valve and the small hole that feeds the tube to the bowl was clogged with calcium. cleaned it out and now i have a spare. changing the valve only took 5 min. and i did not remove the toilet from the floor as per the instructions. but this may not be the case depending on where your toilet is mounted. i had just enough room to get my hand in behind.

Taking my "John" apart tomorrow for the same exact reason; "suddenly" low flow.

(Crappy job for a Sunday).

I have a Thetford Aqua Magic V and the flush valve has a sealed port on it to receive a hand flush wand.

I ordered the flush wand kit when I ordered the new valve.
Stay Tuned. Film at Eleven...

Herk, I put one of those water saver hand helds on my Thetford and it works great. I sure wouldn't call it a "water saver" like they call it, but it's nice to have. I think it would be a considered a water saver if it were plumbed in prior to the flush valve, with water pressure at will. But with it installed in the valve it's not useable unless you activate the flush pedal. That's why I wouldn't call it a water saver....

Thanks for the tip! I had not realised that.

I am putting a shutoff valve in the PEX hose and adding a T nipple for the hose should not be all that much additional trouble.

I need to think about how I will do this.
I might want a regular T fitting and another shutoff valve to the wand.

Film at Eleven.

Herk, when you do this mod,take plenty of pics. I might be re-doing mine so it has pressure regardless if youíre flushing the toilet...

Ran this idea by DW and she had valuable input.

Most likely you would only be using the washer to spray down the sides of the bowl with the tank valve open anyway.

While there might be a time when you would want to wash the sides without the valve being open; it would certainly be infrequent and you could accomplish the same thing using the "half way" position to add water to the bowl while spraying.

So in the long run the plumbing hassle might not be worth the extra time and parts expense. The shutoff valve is still a "go" however.

herk that is the same model i have. when you disconnect the thin flimsy hose take a look in the hole mine was blocked. one screw, the fresh water pipe, hose to the flush port and one linkage rod and it was off. easy job and found instructions on thetford web site.

Thanks Pal. I hope it is that easy. I will have a "boatload" of spare parts if that is all that it is. All the parts for a complete rebuild came in today.

New Nozzle; Flush Valve; and hand wand. Since each kit comes with flange washers so I can remove the hopper and re-seat it three times.

OK, I rebuilt my Thetford Aqua Magic V and added the wand.
The DW LOVES it. I have to say I like it too.
I have tons of photos and a few surprises.
I am going to start a new thread in Mods.

nice write up herk. i never looked at the size of the new hole but i have noticed that it never flushed this good before. what size did you drill it out to. i think i will replace the hose to the flush nozzle as i thought the same as you it is very flimsy. i am going to repair my old valve and keep it for a spare. this looks like it will be a comman trouble for many people. glad you put a sticky on this. wish it was there when mine started to act up.
