# RV Toilet, Sink, and Shower Repair in Chino > We repair and replace the fixtures you touch every day, toilets, faucets, sinks, and showers, and fix the leaks behind them in our Yorba Linda shop before they rot the floor. The toilet, sink, and shower are where plumbing meets daily use, and they are where small leaks do the most quiet damage. A toilet that loses its water seal, a faucet weeping under the vanity, or a hairline crack in a fiberglass shower pan can soak a subfloor for months before you see it. OCRV Center repairs and replaces these fixtures in shop, and just as important, we chase the leak behind them so the floor underneath stays sound. ## Toilet repair and replacement RV toilets are simpler than house toilets but fail differently. The most common complaint is a bowl that will not hold water, which means the ball seal or flush valve has dried and cracked and is letting both water and black tank odor up into the bathroom. We rebuild the flush mechanism and replace the seals, and when a plastic toilet is cracked or a foot pedal is worn out, we replace the unit with a porcelain or plastic toilet that fits the existing flange. The flange seal where the toilet meets the black tank pipe is its own failure point, and a bad one is a steady source of bathroom smell. We pull the toilet, replace the flange seal, and reset the unit so it sits flat and sealed. - Ball seal and flush valve rebuild to stop water and odor loss - Foot-pedal, vacuum-breaker, and water-valve repair - Toilet flange seal replacement to stop black tank odor - Full toilet replacement (porcelain or plastic) to existing flange - Macerating and cassette toilet service where fitted ## Sink, faucet, and drain repair Under a galley or bath sink is where slow leaks hide, and the usual suspects are a worn faucet cartridge, a cracked supply line, or a P-trap fitting that vibrated loose on the road. We pull the cabinet contents, dry the area, and pressure-test the supply so we can tell a faucet drip from a line leak from a drain leak, because they all show up as the same wet cabinet floor. We replace faucets, supply lines, traps, and drain baskets, and we use fixtures rated for the vibration and flex an RV puts on plumbing. House fittings sometimes work, but the connections that last are the ones built for a vehicle that twists down the freeway. - Faucet cartridge, aerator, and full faucet replacement - Supply line and quick-connect leak repair under sinks - P-trap, drain basket, and tailpiece replacement - Galley and bath sink replacement and resealing - Leak isolation: faucet vs. supply vs. drain ## Shower and tub repair RV showers are usually one-piece fiberglass or ABS surrounds, and they crack from flex and from people standing on a pan that was never fully supported. A cracked pan leaks straight into the subfloor every time the shower runs, so this is one of the most common hidden-water-damage sources we see. We repair cracked pans and surrounds with our fiberglass team and reinforce the pan support so the crack does not simply reopen. The valves, the diverter, and the flexible shower hose are the other failure points, and a shower that drips or will not switch between tub and head is usually a worn cartridge or diverter. We replace the valve hardware, reseal the surround to the wall, and run the shower under pressure to confirm the floor stays dry. - Fiberglass and ABS shower pan and surround crack repair - Pan support reinforcement to stop cracks reopening - Shower valve, diverter, and cartridge replacement - Flexible shower hose, head, and slide-bar replacement - Surround-to-wall resealing and post-repair water test ## Frequently asked questions ### My RV toilet won't hold water in the bowl and the bathroom smells. Why? Those two go together. The ball seal or flush valve has cracked, so it is letting the bowl water drain and letting black tank odor straight up into the bathroom. We rebuild the flush mechanism and seals, and if the toilet itself is cracked we replace it to the existing flange. ### I have a crack in my fiberglass shower pan. Can it be repaired? Yes, our fiberglass team repairs cracked pans and surrounds in shop. The key is reinforcing the support under the pan so the crack does not reopen, since most pan cracks come from flex and inadequate support. We also water-test it before it leaves. ### There's water under my bathroom sink but I can't tell where it's coming from. Can you find it? Yes. A wet cabinet floor can be a faucet, a supply line, or the drain, and they look identical until you test them. We dry the area and pressure-test the supply to isolate exactly which one is leaking, then repair it and check the subfloor underneath. --- Source: https://oc-rv.com/services/toilet-sink-shower-repair/ OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887.
