pressure reducing valve leaking
Yesterday, the Taco pressure reducing valve on on the mains feed to our boiler has started to leak (modest drip) after I was using it to purge air from our heating system. Beyond putting a bucket underneath & getting it replaced (if nec.) next week, should I worry? Is it likely to turn from a drip to a flood? Is it just a question of adjusting a screw etc? We have had the system (& the valve) for a few years with no leak. Any guidance would be great. Have called a plumber but not heard yet & until I know I won't cause a flood, I have isolated the valve and necessarily turned off the heat.

Just turn off the valve upstream to limit how much water can come out if it does let go completely.

Thanks for the feedback! I still have a concern that if the mains line in is closed and the valve fails that the pressure in the heating system could drop / water drain out & air into the heating system (causing problems with the circulation pumps etc). Is this realistic or very unlikely/not worth worrying about?

It's realistic but what's the difference?
You know you have to change the valve very soon and you'll have to purge the system of air at that time anyway.
