Will this 31705 kit fit my Thetford Aqua-Magic V toilet?

The Vypart 31705 assembly was designed specifically for Thetford Aqua-Magic V high- and low-profile toilets and supports both hand-flush and foot-pedal models. It covers many factory part numbers, but it's important to confirm compatibility with your exact model before ordering.

• Compatible with numerous Thetford models such as 31646, 31647, 31650–31683, 31705 and related part numbers.
• Supports both hand and foot flush styles used on Aqua-Magic V units.
• Compare your existing valve part number to ensure a match prior to installation.

How durable and weather-resistant is the replacement valve?

This Vypart valve uses reinforced materials and a tighter thread design to resist leaks, cracking and deformation under pressure. The body and cover are thicker than basic aftermarket options and include elastic fiber layers to retain shape and elasticity in variable temperatures.

• Thicker valve body and reinforced cover reduce risk of freeze-related cracking.
• Elastic inner materials improve pressure resilience and maintain sealing.
• Hydrolysis and chemical resistance extend service life in an RV environment.

Is the 31705 kit easy to install while on the road?

Yes—Vypart built the kit to be serviceable with minimal tools so you can replace the module during routine maintenance or a road-side repair. Most installs require just a Phillips screwdriver and a few minutes of basic mechanical work.

• Includes the valve, rubber flange seal and mounting screws—no extra parts needed.
• Simple screw-in installation; follow visual guides or online installation videos.
• Compact design fits into the original valve location without modification.
