Válvulas, sellos y piezas de reparación para inodoros de RV

What RV toilet parts can I find in this collection?

This collection covers the common failure points on RV toilets: flush ball seals, water valves, vacuum breakers, foot pedal assemblies, closet flange seals, hand spray kits, and bowl-to-base gaskets. Most parts fit Dometic, Thetford, and Sealand units. Confirm your toilet model number before ordering to make sure you get the correct fit.

How do I know which RV toilet flush valve I need?

Match the valve to your toilet brand and model, not just the appearance. Dometic 300, 310, and 320 series use a ball-style flush mechanism with a specific seal kit, while Thetford Aqua-Magic V, IV, and Style II each take different water valve assemblies. Check the data label under the toilet base or behind the foot pedal for the model number, then cross-reference it against the part listing. If your toilet leaks at the base when flushed, you likely need a flush ball seal; if water trickles into the bowl constantly, the water valve is the usual culprit.

Can I repair my RV toilet myself, or do I need a technician?

Most RV toilet repairs are straightforward DIY jobs that take 20 to 45 minutes with basic hand tools. Replacing a flush ball seal, water valve, or vacuum breaker requires shutting off the water, disconnecting the supply line, and swapping the part. The OEM service manuals walk through each repair step by step. For odor or holding tank issues that often get blamed on the toilet, our Thetford holding tank chemicals address the root cause rather than the symptom.

How often should RV toilet seals be replaced?

Plan on replacing the flush ball seal every 2 to 3 years under regular use, sooner if the toilet sits unused for long stretches and the seal dries out. A failing seal shows up as water leaking from the ball into the holding tank between flushes, or as sewer odor working its way up through the bowl. Keeping the seal lubricated with a silicone-safe conditioner extends its life. For complete bathroom maintenance, pair seal replacement with proper roof venting from our Ventline vent accessories to keep airflow moving through the holding tank.

Do you carry parts for both plastic and porcelain RV toilets?

Yes. The collection includes repair parts for lightweight plastic toilets (Dometic 300 series, Thetford Aqua-Magic) and full porcelain models (Dometic 310/320, Sealand Traveler). Internal components like water valves and vacuum breakers are often shared across both body styles within the same brand family, but flush mechanisms and base seals are model-specific. Verify the part number on the toilet itself before ordering.

What ships free, and how fast do orders arrive?
