Problem #5: Toilet Troubles
Talk about a problem that stinks; a malfunctioning toilet is an RV repair that requires immediate attention.
Two of the most common RV toilet problems are water failing to stay in the bowl and a valve lets water run continually.
A lack of water in the bowl means that the rubber seals around the large valve are hard or damaged and can no longer do the job. Continually running water indicates that the water valve is not closing completely.
How to avoid: A slide valve seal is going to age; extend its life by keeping the channel around the inside edge clear of toilet paper, calcium buildup and other crud. Apply a liberal dose of seal lubricant to keep the rubber pliant.
The water valve is usually a sealed unit, so there's little in the way of maintenance you can do.
How to fix: If the slide valve gasket continues to leak, your best recourse is to replace it following the manufacturer's instructions. While it will require you to pull out the toilet, replacing the gasket is usually a simple job. Same goes for the water valve.

Problem #6: Leaking Waste Water Valve
If you connect your sewer hose to your gray or black water tank and too much fluid dribbles out when you remove the valve connection cap, it's likely that the slide valve for that tank is no longer sealing properly.
How to avoid: Avoid this RV repair by keeping the channel around the inside edge clear of debris. Also apply a liberal dose of seal lubricant to keep it working.
How to fix: Replacing the wastewater valve is a cinch, as the entire valve is usually accessible from outside your rig and is held in place in the pipe system with four bolts. With your replacement valve assembly in hand, remove the bolts and slide out the old valve and seals. Insert the new seals and slide the new assembly into position between them. Install the four bolts, tighten and you're done.
