Corrosion at the shut-off valve at this London home prevented a full water stop ahead of the toilet service. The tank showed running flapper and fill valve failure, conditions an emergency plumber sees often on older builder-grade units. Running toilet plus a shut-off that will not close? Contact Jumbo for clogged drain and toilet service.

Port Stanley homes with long hot water lines often deal with slow delivery at fixtures during colder months, when ground temperatures pull heat from supply piping before water reaches the tap. Jumbo Plumbing took care of this for a local homeowner by installing a recirculation line and pump tied directly into the kitchen supply. The Navien tankless unit in the basement was already running well, so the work stayed focused on adding the circulation loop. A red-bodied pump is now inline on the return piping, keeping hot water circulating and ready at the kitchen. If your hot water wait times have been bothering you, give us a call. A plumber from our team is ready to help, and any local plumber worth their salt knows this fix makes a real difference in daily comfort.

Flow testing at this London residence confirmed hot water delivery had dropped off at the tub-shower valve. A new single-handle tub and shower faucet was installed by a local plumber, restoring balanced output with a one-year worry-free warranty. Tub faucet not delivering hot water like it used to?

Our technician got this St. Thomas bathroom back in working order after a floor renovation uncovered a supply valve that wouldn't shut off. The homeowner had contractors pulling the toilet for new flooring when the faulty valve became a problem. Our plumber confirmed the shutoff was non-functional and needed replacement before the toilet could be safely reinstalled. The tank internals were checked with the lid removed to confirm fill valve operation after water was restored. Replacing the valve first was the right call, given the toilet needed to come out anyway. Give us a call if you run into the same situation.

Standing water beneath the tank at a London residence confirmed the old water heater had reached end of service life. A high-efficiency forty-gallon direct-vent gas unit was installed by a local plumber with a mixing valve and six-year worry-free warranty. Wondering how much life your water heater has left?

We arrived at this St. Thomas home to find the sump pit dark, water-filled, and the float switch caked in grime, which pointed to a pump that had stopped working overnight. The discharge pipe confirmed the old unit had lost prime and wasn't moving water anymore. Our plumber pulled the failed assembly and checked the crock for any debris buildup that could affect the new installation. A heavy-duty 1/3HP sump pump with a back-water prevention system was then put in, along with all supporting connections. The one-year worry-free warranty covers parts and labor. Book your sump pump repair or replacement with a trusted plumber from our team today.

Leak trace testing at a London home isolated pooling basement water to connections above the shower ceiling bay. Leak detection work included replacing the water meter gasket, swapping four feet of copper to Wirsbo, and correcting a kitchen sink drain improperly tied to the shower.

Tub spouts deliver water through a diverter valve that redirects flow between the spout and shower when activated. A faulty diverter or worn gasket allows water to leak behind the wall or through the tub deck, potentially damaging floors and ceilings below. Our technician responded to a leak complaint at this London home and traced water damage to a failing tub spout assembly. The existing spout showed internal wear that prevented proper sealing. The old spout was replaced and a new Moen Posi-Temp trim plate in chrome was installed to match the existing shower valve. This repair took care of the leak source and got proper water control back. Give us a call if you spot water stains near your tub.

A St. Thomas bathroom inspection confirmed the toilet had shifted from its original position, leaving the base unseated and the wax seal compromised. A loose base is a common sign that the floor flange connection has loosened over time. Jumbo Plumbing reset the toilet, replaced the wax ring, and secured the base to restore a proper seal against the tile floor. The unit was tested to confirm stable seating and no leakage at the base. Any local plumber handling a toilet reset should check the flange condition before reinstalling. Reach out to learn more about what a proper toilet reset involves.

A homeowner in London discovered water damage in their basement bathroom ceiling, traced back to the upstairs toilet. Another contractor had already removed the damaged ceiling due to black mold, confirming the leak's severity. The toilet was inspected and the flange seal had deteriorated, allowing wastewater to seep through the subfloor with each flush. The toilet was removed, and the old wax ring and flange components were stripped away. Heavy-duty two-piece discharge seals were installed for a more reliable, long-lasting connection. The resealed toilet was tested under pressure to confirm no further leakage before completing the work. Schedule your toilet flange repair if you've noticed ceiling stains or moisture below a bathroom.

Jumbo Plumbing visited a St. Thomas homeowner for a sump pump repair assessment on a Liberty unit sitting at the bottom of a pit with standing water and visible age-related wear. The pump had been in service for twelve years, and the float switch assembly and discharge piping both showed signs of extended use. Our technician confirmed the unit was past its reliable service window. A professional dual pump backup system was then installed, including a high-output maintenance-free battery backup component, all labor, and quality materials. The installation now provides a secondary layer of protection when the primary pump is under load. Book your sump pump inspection with a plumber from our team today.

Spring flooding hit West Lorne hard this year. Heavy rain and rapid snowmelt overwhelmed older basement drainage systems all over the area. A homeowner found water pooling in both the downstairs washroom and laundry room. They weren't sure if it was groundwater seepage or a plumbing failure. The water supply was shut off as a precaution while our technician investigated. Inspection showed that wastewater from below-grade fixtures had nowhere to go during peak flow conditions. Jumbo Plumbing installed a heavy-duty half-horsepower sewer ejector pump with a backwater prevention system and overflow warning to protect the space. The system now handles wastewater reliably during heavy rain events. Reach out to learn more about basement flood protection.

A hidden leak beneath the kitchen cabinets had forced this London homeowner to shut off water to the entire house. The technician traced the source to a corroded section of the 1-inch copper supply line, which had been slowly seeping water into the cabinet base. The damage was isolated to a short run of pipe, making a targeted repair more practical than replacing the entire line. The failing section was cut out and new copper was soldered in, matching it to the existing supply system. The repair brought back full water pressure while keeping the rest of the original plumbing intact. Tap to book your next plumbing repair.

Emergency toilet service at this St. Thomas home restored function after an upstairs failure left both bathrooms unusable. The plumber cleared the blockage in the main drain stack and confirmed the downstairs toilet flushed properly. Same-day response prevented further disruption to the household. Toilet not flushing and you have no working bathroom? Phone Jumbo Plumbing for same day plumber service.

Hidden leaks in shower systems can cause major structural damage before homeowners even know there's a problem. A West Elgin homeowner called us after noticing ceiling damage in the bedroom below their shower. The homeowner had already checked the visible drain connections and resealed the caulking, but the leak pattern pointed to something deeper in the shower pan or drain assembly. Our plumber did a full inspection of the modern tile shower, checking the acrylic pan, drain seal, and waterproofing membrane behind the wood-grain tile surround. The glass enclosure seals and threshold were tested too. A thermal imaging scan showed moisture buildup that you can't see with your eyes. Catching these issues early keeps floor joists intact and prevents a full shower teardown. Learn more about our diagnostic leak detection services.

Kitchen sink and faucet installation at a St. Thomas residence used owner-supplied fixtures matched to the existing wood countertop. The plumber connected new ABS drain lines and verified proper slope before testing both bowls. Water flowed without hesitation once the supply valves opened.

Kitchen faucets rely on ceramic disc cartridges or compression valves to control water flow and temperature, with seals that can wear over time and cause drips or reduced performance. A warranty follow-up in London brought our technician back to a recent sink installation where the homeowner noticed the pull-down spray head wasn't retracting smoothly. The inspection revealed minor resistance in the hose mechanism, a common break-in issue with new faucets that sometimes needs adjustment rather than replacement. Food-safe lubricant was applied to the hose guide by our plumber, who then tested the spray function through multiple extension and retraction cycles to confirm smooth operation. The faucet now works as it should. The homeowner was pleased we handled the callback quickly without pushing unnecessary parts. Tap to book your next plumbing service with Jumbo Plumbing.

Sump pump repair at this St. Thomas home addressed repeated alarm activations from the battery backup unit. The plumber inspected the sealed basin, tested the float switch, and verified discharge line flow to isolate the issue. Adjustments to the backup system restored normal operation without false alerts. Sump pump alarm going off and you are not sure why? Get in touch with Jumbo Plumbing for emergency plumber diagnosis.
