I appreciate being able to post this here! Thank you for making this available! I've looked over other posts here and didn't find anything similar to what I am experiencing. Forgive me if I overlooked an answer already posted elsewhere.
I'm not a plumber, but not completely in the dark - almost, but not completely. I'll try to be accurate and to the point. About a month ago one evening, I noticed my water was off. The whole street was off - I assume for an emergency repair. When it came back on, the usual spitting/sputtering/nasty water I've always experienced after the water came back on didn't occur. I was surprised. Not long after, I wish I remembered how long, but don't, I noticed water hammer while my washing machine was filling. I installed a water hammer arrestor on the cold water side (I don't use the hot side), but it didn't help. I then noticed that the hammer (vibration) specifically occurred only when my washing machine or dishwasher were filling AND THEN one of the three toilets were flushed (there are 2 toilets upstairs, one downstairs. The dishwasher and washing machine are downstairs, btw). How it usually happens - the washing machine or dishwasher is filling, then a toilet gets flushed and the vibration starts - usually at the end of the toilet refilling. I added arrestors to all the toilets, but it didn't help. During one hammering event that occurred while the washing machine was filling and a toilet was refilling, i quickly opened the cold water on the bathroom sink, and the hammering went away. I've opened the cold water and stopped the hammering that way on a few occasions. Tonight, the washing machine was running downstairs, and I started using one of the upstairs bathroom sinks, and the hammer started. It was louder than normal. I turned the sink off and it stopped.
I bought a pressure gauge recently, and it was about 60 psi. I have done the drain the house procedure twice. The last time I let the system sit for 40 minutes after all the water drained. It didn't help either.
So, to kind of recap, in most cases I've experienced, if my washing machine or dishwasher are filling, and another source of water is used (so far, it's when anything in the bathrooms are turned on), the hammer starts, and it subsides if a 3rd source is opened. One more thing that I just remembered to mention - when nothing is running, and either of the upstairs toilets are used, when they get to the end if their filling, there is a relatively mild, quick, rapid-fire hammer/vibration. Sometimes the downstairs toilet does that, and other times I hear a soft "wooosh" sound after i hear the fill valve close on that particular toilet.
I have hearing loss, and I can never tell exactly where the hammer is coming from, which is frustrating.
I apologize if what I have posted here is too long winded or confusing, and I really appreciate the opportunity to see if anyone has any thoughts or suggestions. I thank any help in advance.
