All hot taps in house run water but bathroom sink tap only runs for a few seconds then totally shuts off whilst still turned on fully

Hi @theends , Try the following and see if it clears any possible obstruction in the pipe feeding the tap. (be prepared for water to come out under pressure) Having two people to perform the test is advisable, one standing by to turn off the main taps ;-) Shutoff the main hot water tap for the house (usually near the hot water service) and the main cold water tap to the house. Remove the tap handle, spindle and washer from the bathroom sink’s hot water tap fitting (as if you’re going to replace the tap’s washer) Place a rag (or even a bucket upside down) over the tap fitting to prevent hot water going everywhere. Open the main hot water tap and check the flow from the bathroom sink hot water tap fitting. (if there isn’t much pressure open the main cold water tap to increase the pressure flow through the hot water service) Be careful as the water will be hot! Once the hot water flows unobstructed, shut off the main hot water tap (and the main cold water tap if you’ve opened it) and replace the sink’s tap washer, spindle and handle etc.
