In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Customer has a 1 pipe system. The radiators at the ends both sprayed a rusty solution all over after I changed the vents on all the rads. I adjusted water level when I changed out the vents. Went back today to find the spray stains and extra water in the boiler. Manual feed no one has touched it since I was there last. Just looking for some things to investigate when I go back.
