WORCESTER EXPANSION VESSEL PART NUMBER 87161055450
The Expansion Vessel ensures that the boiler can’t over pressurise, this device is designed to allow expansion within the system water when the temperature is raised.
Water, when heated, expands and becomes larger in size, the expansion vessel is designed in such a way that it allows for this expansion to take place in a safe way.
Common faults when these aren’t working are:
1) The boiler constantly requires re-pressurising; this is normally every morning after the heating has been on the previous evening.
2) The pipe that goes to the outside of the property is dripping constantly especially when the central heating is on.
3) If the pipe isn’t connected to the outside of the property then the dripping will be located under the boiler and can be very hot indeed.A good way of checking if the expansion vessel is faulty is to make sure the heating and hot water haven’t been on for 2-3 hours ensuring all the water within the heating system is cold.
Re-pressurise the boiler up to 1 bar on the pressure gauge (please note we can’t be held responsible if the pressure gauge is faulty) then turn on your central heating. If the pressure gauge goes up to 3 bar within in 15-30 minutes and the pipe is leaking to outside, this indicates that you have a problem with the expansion vessel.
The above problems could also indicate that the pressure relief valve is faulty too, we recommend that this is changed at the same time as the expansion vessel.
Please note the above is for information only and is not a diagnosis of your boiler fault, we take no responsibility for a wrong diagnosis of the fault to your boiler.
