help - no heat upstairs - no water

I have a 2 zone american standard boiler with no shut off valve for zone - baseboard heating
I recently drained the system to install a new circulator pump for the zone upstairs

I have bleed the baseboards numerous times and still have not gotten water - only air

I'm only getting 4psi

Any ideas?

Four PSI

At that pressure you don't have enough to push the water to the second floor. You should have about 15 psi. The tenth post in this thread contains a couple of links showing reducing vavles.

I suspect your reducing valve is not functioning properly. Sometimes simply adjusting it will help to flush out debris.

Adjusting pressure

To increase the pressure you need to turn the stem clockwise. You may have to loosen a locknut to do so. Turn only one turn at a time allowing the pressure to stabilize between turns. Usually 5 minutes between adjustments is fine.

baseboard - no heat

Thank you for your help

It turned the flow valve was clogged

However, now we have pressure, we have plenty of water but still no heat

The radiator in the bathroom is now hot...(wasn't before) but all of the baseboards are still cold

We've been bleeding the the baseboards and getting water

any suggestions?

No heat

You probably still have an air pocket blocking the flow. Radiators are a lot more forgiving due to their volume. If you have been bleeding with the thermostat calling for heat, try it with the circulator off.
