vailant boiler

[eddiebrown424]

Hi All,

If I isolated a boiler (combi) and opened the cold feed how much water approx should I expect to drain. Its a vaillant its a turbomax and the customer has no water comming out the hot tap.

Thanks in advance

Eddie

I think he's saying if he isolated the cold supply to the combi then opened a hot tap how much water would come out .
Depends which tap your opening if that's the question

If no water out of hot tap ! then something is blocked in boiler or valve under boiler is closed off what type of filling loop is fitted ? if type with 2 grey taps make sure they are both closed
