If you’ve turned on the outside tap after the winter and the water flow is very poor or does not exist it’s most likely that the non-return valves have become jammed. Many outside taps now have two small plastic non-return valves fitted that will become damaged if the water in the tap freezes during cold weather. There’s little you can do with these, you will probably have to replace the tap. The best solution is to fit a non-return valve to the internal pipe work that feeds the tap.
