2. Detailed steps

An issue you’ll encounter is an RV toilet foot pedal leaking. You’ll notice moisture or a water puddle around the pedal’s base. This issue often results from pipe obstructions, deteriorating gaskets, or faulty seals.

Here’s how to fix an RV toilet leaking at foot pedal.

  • Use a pipe wrench to loosen the nuts and hose connections and remove these fixtures from the RV toilet.
  • Inspect the components – seals, O-rings, and hoses or pipes – and determine whether they require a replacement or repair.
  • Insert a drain snake into the hoses or pipes if you notice clogs or obstructions.
  • Replace worn-out or defective gaskets and seals, ensuring you use only the right products for the toilet.
  • Reposition the components into their correct placements and test the RV toilet. Replacing the RV toilet foot pedal might be necessary if the leak persists.

Suppose you can push the RV toilet foot pedal down, but it won’t rise back up. In that case, you might want to remove RV toilet foot pedal and check for obstructions.

The lever or spring mechanism inside the RV toilet foot pedal can also malfunction. These events can prevent the RV toilet foot pedal from operating normally. Here’s how to fix it.

  • Turn off the water supply to the toilet.
  • Place rugs or towels on the floor next to or around the toilet base.
  • Get a screwdriver to loosen the nuts securing the fixture to the floor.
  • Scoop out water from the tank to make your work less messy.
  • Remove the toilet foot pedal, and then check the spring mechanism.
  • Assess the RV toilet foot pedal for gunk or debris.
  • Brush the obstructions off and clean the component using a soft-bristled cleaning brush.
  • If you suspect a broken spring mechanism or lever, replace it with a new piece.

Sometimes, the problem is not with the toilet foot pedal but the flapper—a valve that opens when you depress the pedal to flush the contents into the black water tank.

Unfortunately, a faulty or damaged toilet flapper broken beyond repair will not flush the toilet’s contents, no matter how much you push the RV toilet foot pedal. So how do you fix RV toilet flapper?

  • Check your manual for instructions on addressing a flapper or ball valve sticking.
  • Assess the ball or flapper gasket for signs of obstruction, such as debris. Remove the obstacles and clean the seals. It could be the only solution you’ll need if an RV toilet valve won’t open.
  • If the previous step doesn’t resolve the issue, cut off the water supply to the RV toilet and switch off the water pump.
  • Wear gloves and open a one-piece RV toilet’s flapper valve. Remove the seal and replace it with a new one.
