My shower has a weak stream. Whats the cause?
A. It could be the pressure is being siphoned off by a filling toilet tank, the dishwasher, washing machine or even an irrigation system. If there is plenty of pressure at other faucets in the house, the culprit could be a showerhead that’s been clogged by hard water deposits. If the blockage is severe, you must remove and clean the shower head. If the blockage is not too severe, you may be able to clean it in place. Pour a cup of vinegar into a plastic bag, place the bag over the showerhead and secure it with a twist tie. Leave it there over night. In the morning, remove the bag and use a toothbrush to gently scrub the softened deposits from the holes.
