SeaLand makes, what I recollect is, ane of the all-time choices for any RV or gunkhole. They're the same size every bit a home toilet. They are made of china, but like the ones at abode. These toilets are not uncomplicated however. Here y'all volition find an explanation of how they work and how to repair them when they stop working. Warning, this is a messy chore.

The leap cartridge returns the pedal to the neutral position from either the upwardly (make full) or down (flush) position. Practice not open up the cartridge, the spring will pop out and you volition not be able gather it again.

Step 6

The toilet flush ball is actually one-half a ball. It's fabricated of plastic and seals the toilet from the holding tank. It has a locking screw on the underside that locks it to the brass ball shaft. The ball has a Teflon seal over it and a safety bowl seal over that.

Footstep 7

After the toilet has been in apply a few years, or bug occur, information technology becomes time to overhaul it. Be prepared for a messy chore. Showtime past removing the corrective pedestal cover. It has only 1 screw on the pedal side. Likewise remove the plastic pedal cover.

Install the new ball shaft dorsum in the hole. The new shaft volition most probable be made of brass instead of plastic like the original shaft. Advisedly insert the brawl upside downwards and attach it to the new shaft with the new spiral.

Place the rubber basin seal on top of the Teflon gasket and place the china bowl on height of the pedestal. Put the two half-clamps in place in the same orientation that they came off. Supervene upon the water hoses. Identify the holding band over the half-clamp with it'south worm screw towards the rear of the toilet and tighten well. Supplant the cosmetic pedestal cover, pedal and pedal cover and turn the h2o dorsum on to test for leaks.
