vaillant 112eh?

Hello the pressure on my guage is way too low can anyone tell me how to raise is, do i need a filling loop?
mcgregor, March 2008
definitely no filling loop, cant find manual on net, not even sure how a loop would fit on

mcgregor, March 2008
There might already be a filling loop underneath, usually a braided pipe. If there is a braided pipe then at one end there should be a screw head. turn that until you can hear water filling up the boiler and then turn it off when the pressure gauge reads wht you want it too.
If you don't have a filler loop then I suggest you download the manual off the internet and see what needs to be done

Yes you need to find the filling loop, open the valve on it and increase the pressure until its around 1 bar on the gauge.
