Many newer mobile homes have an all-in-one mixer type of faucet assembly. To repair leaks, turn off the water at the main shutoff valve. Drain the water lines through the faucet. Unscrew the serrated ring and
lift off the handle.
Inside, you’ll find one or two neoprene cartridges. Inspect the 0-rings on these cartridges and replace them if they look stiff or worn. Good 0-rings are smooth and pliable, with no cracks. If the cartridges themselves appear worn or damaged, take them to a plumbing supplier for replacements. Many of these cartridges carry a 10-year guarantee. Your mobile-home dealer or manufacturer can advise you on yours. But make the repair before deeper damage occurs.
Clean corrosion from the assembly with a solution of baking soda and water. Before you return the cartridge to the assembly, lift out the springs and washers. Replace any that appear worn, as they too can contribute to leaks.
Reassemble the unit and try it for leaks. If you still haven’t repaired the faucet, call for a plumber or at least ask the advice of your plumbing supplier.
