recentley had tech put in new expansion tank and inlet pressure valve that has no adjustment on it.like the other one did . boiler model is dv.heat is working.but in the bathroom upstairs -it is a medium ranch house.the vanity insalled in 1974 covers one of the baseboards completly the other baseboard in is on the other wall.heres the question how come after 40 years the baseboard under the vanity sounds like theres water running -not the sound of air in the pipes. but like a toilet refilling.the baseboard to the right of does't have this sound. never had this sound before.these are the return pipes to boiler .the output pipe has no sound like this. could it be to much pressure. or is my bell and gosset pump on it's way out? here's the other part. the boiler pressure gauge at rest or in off position reads 25 psi. when heated and running it reads 36 -38 psi. the the tech said the gauge is off not to worry .because if it was right the pressure valve would be spewing steam an water.
