Noisy Boiler Pipes

Jack Smith

Have a customer who is complaining of noisy pipes during heating cycle. I have explained that it is caused by the expansion of the pipe. I believe there is inadequate room for expansion as the riser to the baseboard is pinned against the floor opening where it needs the room to expand. The customer does not want to open the dining room ceiling for access. Has anybody done anything to slow down the expansion process by flow or temperature? Any feedback would be helpful. Thanks!

ODR helps, anything to lubricate the point of rubbing, spray product, wax paper etc. Might never go away sometimes physics is hard to stop.

The worst offender you will ever find is PVC drainage pipes in holes that are too small.

It takes time, but you have to do everything possible to keep pipes from rubbing on wood. If you come behind someone that didn't, you're screwed. Scrap pieces of copper, zinc, lead or aluminum flashing material can be a wonderful thing if you want a silent job.

lower temps might help, but only way to get to the root of the problem may be to rip into the ceiling

You can try inserting pieces of a plastic milk jug around the binding areas.

If the risers are too short would there be a chance of unsoldering the copper 90's; add a coupling and stub or a coupling & street 90 into the coupling; this would push the horizontal pipe down at least 3/4". Just a wild hair idea and easy to suggest from a 1000 miles away.
