I just moved to a new place. And since the building is old there were a lot of problems with it. So I contacted the manager but he didn't want to fix all of them. He always gives me excuses not to fix it, saying that nothing was promised to you. I think he doesn't want to fix it because he is shady and cheap.One of the problems I have is the boiler. Every time I take a hot shower, the boiler starts to pump water. By doing that, it makes loud noises! I told the manager about this and his reply was: There is nothing wrong with the broiler. Hot water pipes in the walls tend to knock when in use due to expanding. The problem is that the noise isn't coming from the pipes, it is coming from the boiler itself. Since I don't understand much, I was wondering if that is normal or not.Like I said before, I don't think my manager likes us. So I think he said that so he doesn't need to fix/replace it.Opinions/Suggestions anyone?
I would be surprised if the hot water comes from the boiler, usually a simple water heater is used. Water heaters growl, rumple and sound like something is swirling around inside when they have not been drained and cleaned out periodically. This is just calcium, iron and / or other minerals that have deposited themselves in the water heater. Other than being annoying no major harm is being done. It would result in lost efficiency of the heater and require more energy to be consumed to heat the water. That would be a minor problem for you if you pay the utilities. It would possibly decrease the life of the water heater but who cares? Right.
If a sputtering supply of water comes out of the hot tap, the most likely cause is an airlock in the hot water pipe. The mains pressure of the cold water is much greater than that of the hot water, so you can use this to force a bubble of air back up the hot water pipe to the hot water cylinder. There are two ways of doing this. Say you have a sputtering tap in the kitchen.If your washing machine is connected to a hot and cold water supply, you can fix an airlock quite readily: ?Turn off the cold water tap at your washing machine and disconnect the hose from the back of the machine. ?Turn off the hot water tap and disconnect the hose from the tap. Now connect the free end of the cold water hose to the hot water tap. (You should now have the two taps connected to each other by a hose.) ?Turn on the hot water tap and then the cold water tap. Leave both taps on for approximately 30 seconds (CAUTION: no longer, because you don’t want to overfill the hot water cylinder). This’ll allow the greater pressure of the cold water to push the airlock back up the pipe. ?Now check the flow at the hot water tap in the kitchen. If there is no improvement, follow the same procedure again. If after three attempts the problem isn’t solved, you‘ll need to call a plumber Another method is to use the mixer tap in the kitchen (or bathroom). Read all the instructions below before you start. ?Jam a cloth over the tap outlet and hold it firmly in place with the palm of your hand to prevent any squirting or flowing from the outlet. (Wear your wetsuit just in case!) ?Turn on the hot tap and then the cold for 30 seconds (make sure it’s in that order to prevent the mains pressure from forcing your hand away). The cold supply will now run through the mixer and across into the hot water pipe, clearing the airlock. Allow the taps to run for 30 seconds, then turn the cold water tap off first, then the hot.
