The water, hot and cold, runs normally in the house except in one of then.we closed and opened the water valve under the sink, no water stiil. How we can solve the problem before we call the plumber

Hi marcel and welcome, If you look to the right side of this page under Similar threads you'll find good info. If you still need help post back with more info. There're some great plumber here. Good luck

Hi Marcel

Try removing the aerator at the end of the faucet... any water flow without the aerator in place? If so, clean the aerator and reinstall it... should be all set now!

Back to you...
