Our Unvented Cylinder Work
Two examples of our unvented hot water cylinder servicing and fault diagnosis in Salford and Cheadle.
OSO unvented cylinder service
We carried out a service on an OSO unvented hot water cylinder at an apartment in Salford M5. The visit included checks of the heating elements as part of the service.
Santon cylinder: poor flow repair
The utility room and three bathrooms had very poor water flow, while the kitchen and outside taps were unaffected. Flushing a toilet could reduce the shower flow to little more than a dribble.
Flow and pressure tests traced the fault to the multibloc valve serving the Santon Premier Plus cylinder and balanced cold supply. We fitted a replacement valve and restored the water flow.
Common Cylinder Problems
A symptom can have several causes. We check the cylinder and its associated plumbing before recommending a repair.
No hot water
A cylinder that stays cold or heats intermittently may have a fault with its thermostat, immersion heater or controls. We investigate the cylinder and its associated components to identify the cause.
Poor hot water flow
Reduced flow can come from restrictions at taps, shower outlets, inlet controls or elsewhere in the system. We check where the restriction starts before recommending a repair.
Dripping tundish
Dripping or running water through the tundish can relate to the expansion vessel or internal air gap, pressure controls or safety valves. We check the system to identify the cause.
Leaks around the cylinder
Water around a cylinder can come from a valve, joint or pipe connection as well as the cylinder itself. We locate the source of the leak and assess the repair needed.
Annual Cylinder Servicing
Regular servicing checks the condition of the cylinder and its safety components. Manufacturers including Megaflo and OSO recommend an annual service, with the work suited to the particular model.
We follow the manufacturer's maintenance requirements and record the work carried out. Tell us about any existing leak, loss of hot water or other fault when booking, so we can allow for diagnosis as well as routine servicing.
Keep your service records: regular maintenance may be a condition of the manufacturer's warranty.

Service visits, repairs and fault investigations from properties in Greater Manchester and nearby areas.
Temperature relief valve replaced
Water was running through the tundish as the cylinder heated. We identified a faulty temperature relief valve and replaced it.
Megaflo multibloc valve replacement
The multibloc valve on a Megaflo unvented cylinder was leaking, with water also dripping through the tundish. We replaced the faulty valve.
No hot water: damaged fused spur
No hot water from an OSO cylinder. We traced the fault to a heat-damaged fused spur supplying the immersion heater and replaced the damaged unit with a double-pole switch.
Thermostat and wiring repair
No hot water from an open-vented cylinder. A loose connection had overheated, damaging the thermostat and wiring. We replaced the damaged thermostat and wiring.
OSO cylinder service
Servicing an OSO unvented hot water cylinder, including component checks and testing of the system. The visit covered the cylinder's operation and the condition of its associated components.
Megaflo flow investigation
Investigating poor hot water flow at a property with a Megaflo cylinder. Crystallisation and debris were found at shower components, with further findings indicating an internal cylinder fault. The customer was advised about manufacturer warranty options and further investigation.

View All AreasFrequently Asked Questions
How often should an unvented cylinder be serviced?
An annual service is recommended for many models, including Megaflo and OSO cylinders. Follow the requirements for your particular cylinder and retain the service records for any relevant warranty conditions.
Why is water dripping through the tundish?
Possible causes include a problem with the expansion vessel or internal air gap, pressure controls or a safety valve. The cause needs to be diagnosed. Do not block or cap the tundish or its discharge pipework; continuing discharge should be assessed by a competent engineer.
Do you repair Megaflo and OSO cylinders?
Yes. We carry out repairs, servicing and fault diagnosis for Megaflo and OSO unvented cylinders, as well as Gledhill, Joule, Telford, Santon and other makes.
Why is the hot water pressure or flow low?
Restrictions can occur at individual taps or shower outlets, in inlet controls or elsewhere in the system. Tell us whether the problem affects one outlet or the whole property, and whether the cold water is affected too.
Does the whole cylinder need replacing?
Not every fault requires a new cylinder. Problems with valves, controls and connected pipework may be repairable. We assess the system before advising on a component repair, replacement or further manufacturer investigation.
Can you give a quote from photographs?
Photos help us identify the cylinder and its visible components. Some work can be discussed in advance, while faults affecting heating, flow or safety devices may need an on-site inspection before the repair and parts can be confirmed.
Do you carry out gas boiler repairs?
No. Our cylinder work covers the hot water cylinder and its associated plumbing. If an investigation points to a gas boiler fault, we will explain the findings so you can arrange the appropriate boiler repair.
