How to Replace an RV Toilet

How to Replace an RV Toilet
In under an hour, you can replace your old RV toilet with a brand-new one. The job requires a few simple tools. Old stools may be stuck to the floor and need a little muscle to lift off. Others will lift right off with ease. Keep your work area organized and clean for a speedy process.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:
  • Wrench Old towels Newspapers
  • Wrench
  • Old towels
  • Newspapers
Step 1
Clean up the area around the RV toilet and remove anything that might get in the way. Place old towels in another area where you can place the old toilet while you install the new one.
Step 2
Turn off the water pump in your RV and flush the toilet to alleviate any pressure or excess water in the lines.
Step 3
Look for a plastic cover at the bottom of your RV toilet. It will either rest on each side of the toilet or wrap around it. Pull it up and remove. You can also pull it out toward you if it feels stuck.
Step 4
Locate the nuts and bolts underneath the plastic cover and use a wrench to unscrew.
Step 5
Lay down an old towel down around the toilet to catch any excess water or drips. Lean behind the toilet and find the hose connected to the top back. Unscrew any nuts and bolts.
Step 6
Pull the toilet straight up from the floor. Rock it and twist it gently if it appears stuck to the RV floor. Set the old toilet out of the way on old towels or newspapers.
Step 7
Replace the rubber cone-shaped gasket that seals the toilet to the floor and keeps sewage from leaking. Just lift it off and replace with the new one that came with your toilet. Place your new toilet on top of the ring and line up the bolts into the holes in the bottom of the toilet.
Step 8
Replace the nuts over the bolts and tighten snugly. Do not attach so tightly that you can't unscrew them again. Sit on the toilet and move around to see that it doesn't wobble or come loose.
Step 9
Reattach the hose to the toilet and tighten the nuts over the bolts. Refrain from stripping or attaching them too tightly.
Step 10
Turn the water back on and flush the toilet to check for leaks. Clean up your work area and properly dispose of your old toilet.

Tips & Warnings

 
Measure both toilets and your bathroom area to ensure a proper fit. Check to see if the water connection needs to be shortened with your new toilet. Contact a dealer or a plumber with RV experience to determine if your toilet can be fixed instead of replaced.
