The water within my upstairs bathroom had only just not been getting hot surrounded by the shower, the sink was fine as be the rest of the house. Well, my husband has a friend whom is a plumber that come out and pulled something that looked like a wooden golf nouns out of the line and he replaced the cooper pipes and the faucet. Well, very soon there is no hot hose coming out of the pipes in the upstairs and downstairs bathroom but the marine in the kitchen and adjectives of the sinks gets hot satisfactory to scald you what's the deal. We hold a gas heater by the process but it is one that doesn't have a pilot street light.
Answers:    you either hold a valve to be precise turned off. a blocked or obstructed hot wet line, or a frozen hot sea line (note hot marine pipes freeze before cold hose down pipes do). Thar gold nouns looking thing might enjoy been a faucet wrench or a mixing bowl wrench to remove the nuts holding on the faucet to the sink and the lines also
I have no clue in the region of the golf tee entity, but check your shut off valve; he may not have turned them subsidise on since it is now affecting two bathrooms.
