I shut off my watervalve on a sink in my basement but it was leaking so I shut off the main to put a new seal in it now when I come upstairs to turn on my kitchen sink I have no water at all. I've tried to close the vales and reopen them and let bathroom faucet run but pressure is low in bathroom and no pressure at all in kitchen. Help

Check your aerater at tip of the spout on both kitchen and bathroom sink. The aerater will twist off counter clockwise. See if you have better flow with it off. If so, clean it and reinstall. Please let me know if this helps. This is a very common problem after shutting main water to house off.
