The water that discharges from a tap should come out with sufficient force. Some taps are undoubtedly better than others, with a greater flow of pressure, but in general we know what to expect. Therefore, when faced with a tap that has a poor water flow rate you can figure that something is wrong. Before condemning the whole system of pipework, consider that it may be the tap itself that is faulty. Does it operate freely and open fully? Look at the pipework and see what else is served from the same section, and check out these also. A Lee Plumber would check. Are they suffering this lack of flow? If so, has the problem been getting worse or is it a sudden drop in pressure or flow? Clearly if several taps are affected there is a problem in the pipeline and this will generally be one of the following:Turned off or closed down a water supply.A blockage due to debris in the storage tank.A plug of ice.Corrosion or limescale buildup.The first thing to do in this situation is to look for the source of the water that is being blocked. A Grove Park Plumber knows what to look for. If the problem occurs suddenly, and is affecting the cold water mains supply to the kitchen sink tap, possibly with the flow stopping completely, it may be worth phoning your water supplier as they are may have turned off the water for some reason. For your low pressure pipework, such as that serving the hot and cold taps to the bathroom, check whether the storage tank in the loft is full of water. Is the lid in place, ensuring vermin have not got into the vessel, drowned and sunk to the bottom, blocking the outlet pipe. The weather will be a sound indicator of whether a blockage is due to ice.“
