For the past two months the water valve on our Thetford Aqua Magic V has been leaking and getting worse. Using the trusty DuckDuckGo internet search I found that this is a common issue with these toilets. I decided to go with the Beech Lane BL-112 valves as it is supposed to be an upgrade. It also has a lifetime warranty. At the same time I thought I would do the ultimate in upgrades. I purchased the Thetford Water Saver Kit which is just a spray wand.
Most internet installations has you pulling the toilet out. I guess if you do not have the room between the toilet and maybe a wall, you might have to pull the toilet, but I had plenty of room to get a screw driver in there to remove the one screw. The kits do come with a new toilet seal, so now I have two, but I wanted to avoid pulling the toilet at all costs for all the obvious reasons.
It was really easy. Unscrewed the water line and a small towel caught the little water that came out of the valve.
Word of advice, make sure the water is off before you start disconnecting the water line. Need I say more.
Then take out the one screw holding the valve in place. There is also a pin in the valve that goes into a hole in the toilet that also holds the valve in place. The valve has a groove in it that slides into a slot in the toilet so that it is properly located on the toilet. You need to lift up on the end of the groove to get the pin out of the toilet and then the valve will slide out.
At that point you can gently remove the flush tube from the valve and then lift the valve up to remove the metal rod out of the foot pedal lever.
The new valve has a capped barb fitting for the Water Saver sprayer. It is an option so you need to cut off the end of the cap.
Once the cap is removed you can attache the spray wand hose. I soaked the hose in hot water for a minute and it slipped right on. No real need for the hose clamp, but I used it anyway. Better safe than sorry.
Next insert the metal linkage into the pedal lever and then start to slide the groove in the valve into the slot in the toilet. Then carefully slip the flush hose onto the fitting in the valve being careful not to unseat the small red o-ring. This will prevent the flush hose from leaking.
Now slide the valve all the way into the toilet and secure it with the screw. And there you have it. A new valve and a sprayer.
If you have any questions on this install, please let me know.
