A common issue with Combination Boilers is the Diverter Valve. This tends to be one of the weaker links in the boiler system as its design requires the valve motor to be isolated from the boiler system water.

Typically, this is achieved by passing a connecting rod from the motor to the valve via seals to prevent water leakage. Over time these seals fail and start to leak.

Until recently the only option was to replace the entire valve at considerable expense. This prompted us to develop our patented tools as part of the Fit Once (tm) range so that the valve could be retained and only the leaking internal cartridge replaced.

Now the whole Diverter Valve is fitted just once by the manufacturer saving time, money and unnecessary waste.
