lost water pressure

I shut the water off in the basement to install new valves in my upstairs bathroom. When I finished I turned the water back on but now its running very slowly (in both the hot water and the cold water)and in not only the sink but the tub and toilet too. What do I do to rectify this???

Re: lost water pressure

If this is galvanized plumbing, when you turn the water back on a piece of debris or rust can get caught in some of the restricted areas like joints or 90s and severely restrict the flow. No real good solutions except to cut the pipe and examine the interior. If it is calcified severely the only choice is to replace the plumbing. Copper does not calcify and always looks very clean inside so can't diagnose a problem if it is copper.

Re: lost water pressure

Newer plumbing fixtures have flow control mechanisms on them. Therefore, your old fixture may deliver up to 5 gallons per minutes while the new one, less than 2.
