So I actually have 2 questions. I am on well water, have a new pressure tank, and a tankless hot water heater. My hot water pressure is great but my cold water pressure is horrible. I do have a water treatment system and the utility sink next to the treatment system has good pressure for both hot and cold. Can anyone give me some guidance on what it could be or what I should check?
Also, when I fill the tub and then drain it, water often comes up my sink that is several feet away. I did not do the plumbing in that bathroom and it is under a cement floor so I am not certain of what is actually happening there.
Thanks for the response. The house is OLD, built in 1936. New plumbing was put in throughout the house over the last 8-15 years as things were remodeled and updated. Your response is interesting as I sometimes have my washer not fully drain. I never thought of that be related but maybe it is? The actually plumbing from the utility to the sinks are probably 8 years old. It goes home-treatment system-utility sink. Arteriosclerosis? Sounds serious? Maybe I need a surgeon! LOL!
