This electric toilet overhaul kit (complete set) contains the primary hard parts needed to refurbish a worn or damaged pump assembly. If your marine toilet no longer pumps as it used to, if the pump housing is cracked or deteriorated, or if the macerator blades have become dull/damaged by debris, this kit allows you to replace all those components at once without buying an entirely new toilet system.
What the kit includes:
- A new pump housing – the plastic main body of the pump where the motor mounts and which contains the impeller and macerator. This part often suffers from cracks or stripped screw holes over long use; the new housing provides a solid, leak-free foundation.
- A new macerator assembly – the impeller with sharp blades that grinds the waste. Over time, blades can dull or bend from hard objects; replacing them restores effective waste chopping and prevents clogs.
- A joker valve (one-way discharge valve) – the rubber check valve on the toilet’s outlet that stops waste water from backing up into the bowl. The new valve ensures a tight seal and no backflow, which is crucial for odor prevention.
- Additional fittings and hardware – may include mounting screws, washers, clamps or other small items needed to assemble the above components onto your existing motor and bowl.
Advantages: With this comprehensive kit, you are essentially replacing the “heart” of your toilet (the pump mechanism) while reusing the solid parts like the electric motor and ceramic bowl. After the rebuild, your toilet will function like new – delivering full pumping power, reliable waste maceration, and no leaks or bypass. This is significantly more economical than purchasing a brand-new toilet and reduces waste (an eco-friendly approach by extending your equipment’s life).
- When to Use: If you observe cracks in the pump housing, chronic leaks around the base, or that the toilet isn’t macerating waste effectively (frequent clogs), it’s time for an overhaul. This kit is meant for exactly those situations, to replace everything that’s worn out.
- Cost Savings: Rebuilding with a complete parts kit usually costs far less than a new toilet. This is especially beneficial for higher-end models or when on a budget – you achieve like-new performance without the big expense.
- Installation: Fitting the new parts requires moderate DIY skills – follow the manufacturer’s guide or schematic. Typically, you’ll remove the motor, take off the old housing, swap in the new macerator and valve, then reassemble with new seals (it’s recommended to use a new gasket kit in conjunction).
- Result: After the repair, your toilet will operate smoothly and securely. The pump will build proper pressure, waste will be expelled quickly and finely chopped, and the risks of leaks or odors are greatly reduced. You’ve effectively extended the life of your system by years.
