how can i fill the preassure on my ariston boiler, i cant see any levers, it has two white plastic covers with holes in on two different pipes underneath the boiler but they just keep turning,
Hi Karen,
My water tap is underneath the boiler roughly in the middle.
Its a small black tap, and you turn it clockwise i think.
Keep an eye on your water pressure until its up to 2 and then turn it off.
I check the pressure every so often.
Hope that helps.
Pam.
