No cold water in bathroom

Author: sharklife16 (OH)

I recently updated my shut off valves to the house with new compression 1/4 turn valves and now the downstairs bathroom does not have cold water flowing. The kitchen and the upstairs bathroom work fine. I've also noticed the toilet only fills when the bathroom sink (hot and cold) faucet is on, then stops when faucet is turned off. The shower also has no water either hot or cold. I've taken the supply hoses off to check water flow and i can only get water out briefly when the hose end is closed and some pressure builds up. If anyone has any ideas that would be great. I'm stumped.

If there is a restriction in the cold water feed to that bathroom group, when you turn the faucet on hot and cold it sounds like the hot water is back feeding through the faucet and allows water to go to the toilet. If the shower is pressure balanced, a lack of cold water to it will also prevent hot water from flowing. You need to hunt down where the cold water feeds that bathroom group.
