Hi, Hope you can advise me please,. All I got is a yellow and a black leaver, I’ve not had any issues with the pressure yet but was wondering if it’s the black leaver I use.? Thank you
Hi @@axellex2077 I’ve been advise it’s actually the upstairs boiler which you would use if any loss of pressure,. I’ve had a look at mines and right enough it’s got the taps there,.👌🏼. If you have an upstairs big boiler have a look,. Hope all works out good for you,. 👍🏼👍🏼
