From no Water Hammer to Floor Shaking
I do not know who to turn to for an issue i am having and maybe someone here can help me. I had a very old boiler replaced that had worked very well for about 80 years. it was an oil boiler that was converted to gas and is a one-pipe steam boiler setup and on top of that it was insulated with asbestos. No one ever wanted to work on the thing, so i would just do minor maintenance myself by just draining it once and a while, it was replaced last year with a crown boiler and now i am experiencing an abundance of water hammer and the person that installed has almost no clue to what he is doing. the part that angers me is that this is my grandmother that is going to end up being taken advantage of. first she is being told that there is sludge or dirt in the pipes, and i can understand this and i constantly change out the water in the new furnace, and it isn't crystal clear but it's not sludge... I'm 30 years old, and never in my life have i heard this much water hammer come from our One-pipe setup. It was literally day and night with this new furnace. Went from no water hammer and good heat, to unbearable and possibly dangerous and consistent hammering
The following now happens but never did
Downstairs closer to the boiler, you hear the "marble effect" type water hammer, where you hear water cruise from end of the pipes to another
The water hammering does not discriminate, It happens everywhere in the entire system. Every pipe is pitched toward the boiler to some degree, (there may be 1 pipe that is level). all the radiators are pitched toward the inlet valves.
The inlet valves are all leaking from the valve knobs, they hammer at the inlet valves themselves as well.
and this is not a noise that is tolerable, it's not like a tink tink tink... it is more of a BANG BANG BANG until that radiator is completely hot.. and the pressure release on the radiator is not consistent at all. you can clearly hear that the pressure varies, and this is when the hammering is happening.
personally i feel the issue is due to the pressure in the system not being consistent. There seems to be much to much pressure going to the system in general, the inlet valves do not seem to be able to handle it, they all leak water while the system is active.
the person who put in the system is now saying that the pipes may need to be replaced, because of buildup of whatever is inside them. which for 80 years didn't do anything but all of a sudden is having it's effect.
I am looking to get in touch with someone who may have experience with this type of setup and issue. Thank you very much
