Water Hammer Problem?
Hi All,
I've got a 60-year old house with a water hammer problem. The hammer is particularly noticeable with the cold water line and the two toilets (might be with the dishwasher hot water line too, but I haven't noticed this). The water pressure also seems high. I realize the long-term solution is to replace the pressure regulator, but due to its location this will be a nasty several-day project (previous owners finished the basement and drywalled over it). I'm wondering if I could address it in the meanwhile with some water hammer arresters? Can I just sweat them into some exposed copper lines I have? How many do I need to put in? Does one hot and one cold do it, or do I need to scatter them around? The house is plumbed with copper, but the way it's been done it's a hassle to get at the toilet plumbing. Some people have also suggested an expansion tank. Is that a solution? How do they work? Finally, I could also probably put in a couple of 5-foot air columns in the utility room. I realize they gradually fill with water, but maybe if I put a stop-cock on the bottom I could drain them from time to time? Thanks in advance - Any advice is appreciated.
