What a shower fitter and bathroom plumber repairs
A shower repair can involve the valve, cartridge, head, hose, pump, waste, tray, enclosure, pipework or electrical supply. A bathroom plumber also deals with leaking basin and bath wastes, failed isolation valves, dripping taps, toilet fill valves and concealed leaks around sanitaryware. We begin by reproducing the fault and tracing it to one system. A leak that appears beneath a shower may come from the waste or supply pipe rather than the tray seal; poor temperature may originate at the cylinder or combi boiler rather than the mixer. Correct diagnosis protects finished surfaces and avoids replacing serviceable equipment.
Electric shower repairs
An electric shower takes a mains cold supply and heats it inside the unit. Low temperature can result from restricted flow, a scaled heater can, a failed microswitch or an electrical fault. No power, a burning smell, visible heat damage or repeated breaker and RCD tripping means the unit should be isolated and left off. We check the water supply and appliance fault, while fixed-circuit testing and connection work is completed by a qualified electrician. Replacement must match the cable, protective device and available water pressure; fitting a higher-kilowatt unit without checking the circuit is unsafe.
Aqualisa shower repairs
Aqualisa systems range from conventional thermostatic valves to digital processors installed in lofts, cupboards and under baths. Common problems include temperature drift, intermittent starting, a processor that runs but delivers no water, damaged data cables, stiff cartridges and leaks at connections. We identify the exact range and serial details before parts are ordered because controls and processors are not interchangeable. Where a current repair kit is available, we repair and recommission the shower. If the processor is obsolete, we explain compatible replacement routes without disturbing sound pipework unnecessarily.
Mixer, thermostatic and digital shower faults
A mixer shower needs stable hot and cold supplies. A worn thermostatic cartridge can make the outlet too hot, too cold or slow to react, while blocked strainers and check valves reduce flow. Digital showers add a processor, controller and communication cable, so the symptom at the control does not always identify the failed part. We clean filters, verify supply temperatures and pressures, test the cartridge or processor and set the safe maximum temperature. In homes with children, older people or vulnerable occupants, dependable temperature control is a safety issue rather than a comfort extra.
Leaks from trays, wastes and enclosures
Water on the ceiling below does not automatically mean the tray has failed. We test the waste connection, trap, supply joints, valve penetrations, enclosure seals and tray movement separately. Silicone cannot compensate for a tray that flexes or an untanked wall junction. If the tray and structure are sound, renewing the waste or seal may solve the problem with minimal disruption. If the base moves, the floor has softened or water has tracked behind tiles, the correct repair is to open the affected area, restore support and waterproofing, then make the finish good.
Low pressure and showers running hot and cold
Weak flow can come from a gravity-fed supply, blocked filters, a failing pump, undersized pipework or a combi boiler that cannot sustain the selected shower head. Temperature cycling may indicate an unbalanced mixer, scaled heat exchanger, low boiler flow or a clogged cartridge. We measure hot and cold flow and pressure rather than fitting a pump automatically. Pumps are suitable only where the source can supply them; they must not be connected directly to unsuitable mains or combi arrangements. The result should be stable, safe performance, not just a stronger first minute.
Repair, replace or upgrade
Repair is the best value when a cartridge, control, seal, waste or serviceable processor has failed and the rest of the installation is sound. Replacement makes sense when the body is cracked, the unit is electrically unsafe, parts are obsolete or repeated faults show the system is poorly matched to the property. An upgrade may improve temperature stability or accessibility, but it should follow flow, pressure and electrical checks. We give a repair option where one is practical and a separate written replacement quotation where it is not, so you can compare cost and disruption.
How the bathroom repair visit works
Before arrival, tell us the shower make, model and symptom and send a photograph if possible. On site, the engineer protects the area, isolates water and power where necessary, tests the fault and identifies any concealed-access issue. We explain the diagnosis and labour charge before work proceeds. Stocked service parts may be fitted on the visit; branded cartridges, processors and trims are ordered against the model details. After repair, we run the shower through its temperature and flow range, inspect for leaks and show you the controls and safe isolation points.
