The Thetford Aqua Magic Style II is a popular brand of RV toilet, known for its durability and ease of use. However, like any mechanical device, it may occasionally require repairs. One common issue that can arise with this toilet is a faulty water valve. The water valve is responsible for regulating the flow of water into the toilet bowl, and when it malfunctions, it can lead to problems such as a constantly running toilet or a lack of water in the bowl. To repair a faulty water valve in the Thetford Aqua Magic Style II, there are several steps that can be taken. The first step is to turn off the water supply to the toilet.
Well changed the valve went on pump and now hardly any water flows into the toilet bowl. Well shoot! Looking at the back of the toilet a water hose runs from the output of the water valve up and into the back of the toilet into what looks to be a small plastic vacuum breaker (accumulator oneway valve) that is then attached to a water defuser inside the toilet bowl by a 1.5" short hose. Removed the spring clamp and took the vacuum breaker off the back of the toilet, turned the pump on and using the toilet foot pedal shot water through the valve into the shower. Some junk came out of the line but it had very good pressure. Now for the defuser inside the toile bowl, removed that and it was almost totally plugged up with lime and sediment. Soaked it in straight vinegar for a few minutes and used a small piece of safety wire to poke the holes to make sure it was open. Hooked the defuser to the vaccume braker outside of the toilet, then using the toilet foot pedal shot water through the breaker through the defuser aimed at the shower and now all is well! Reinstalled the defuser back inside the toilet bowl, hooked the hose back up and now all fixed!

The first step is to turn off the water supply to the toilet. This can usually be done by turning a valve located near the base of the toilet. Once the water supply has been shut off, the toilet can be disassembled to access the water valve.
Thread: Thetford Toilet Wont Stop Running
Wife told me this morning that the toilet wont stop running water and that the water pressure was way lower than normal. I thought it must be the water valve stuck. Looked into it and yup when the foot pedal was pressed water ran in and yes it was at way lower than normal pressure, and when the foot pedal was released water kept running in also at way lower than normal pressure but it kept running.
First things first, shut off city water and go over on internal tank and pump. Keep pump off when water not needed. Started to look for a Thetford water valve. Looked on the RV build sheet, the toilet is listed as a Thetford 42072 Style II. Actually on the back of the toilet the model is listed as 42070 but none the less the water valve replacement kit is part number 42049. With that you get the two pieces of the valve and Oring, rubber stopper valve and spring and the toilet base Oring. There are several U tube videos on how to replace the valve. Easy takes a few minutes, the hardest part is getting the foot pedal off and on. I included a pic before taking the valve apart. I DID NOT remove the toilet to work on the valve, with our floor plan there is plenty of room to get at the valve.

Truth be known the problem wasn't the water valve at all, its was the defuser inside the toilet bowl all plugged up with lime and sediment bits. When flushing the toilet the defuser hose was being pressurized since the water could not flow out through the defuser. What water could flow out, it was taking a long time for the pressure in the defuser hose to dissipate and finally stop. It looked like the water valve was bad. All those campgrounds with bad heavy iron water wells will do a number on RV systems.

The location and method of disassembly may vary depending on the specific model of the Thetford Aqua Magic Style II, so it is important to consult the user manual or manufacturer's instructions for guidance. Once the water valve has been accessed, it can be inspected for any obvious signs of damage or wear. If the valve appears to be damaged, it may need to be replaced entirely. This can usually be done by unscrewing the old valve and installing a new one in its place. If the valve does not appear to be damaged, it may simply be clogged with debris or mineral buildup. In this case, the valve can be cleaned using a mixture of water and vinegar. The vinegar will help to dissolve any mineral deposits, while the water will help to flush out any debris. After cleaning the valve, it should be reinstalled and tested to ensure that it is functioning properly. In conclusion, the Thetford Aqua Magic Style II is a reliable and easy-to-use RV toilet. However, it may occasionally require repairs, such as repairing a faulty water valve. By following the steps outlined above, it is possible to repair the water valve and restore the toilet to proper working order..
