They shake because, the water exerts pressure when running in the pipes
You may have air in your water lines
the hot water pips shake because it is passing water throw them and when they do that it can shake and rummble lol
Because when the water freezes it expands.
It is the water rushing through the pipes creating a pumping sound
Strap and secure pipe to stop shake and noise. Drop in pressure is normal. Try using water on off peak times (if city water).
Funny Not really usually but if you do, then you have yourself really thin pipes. Its not that its a problem, its just that your pipes are thin and not that thick. I f i were you i would get myself some thick pipes
You know it by touching and feeling the pipes on the hot water side; if they are hot, there is water running through the pipes and obviously the heater valve is open on hot side.
Fill with anti freeze solution or keep the water running.
No, The refrigerant within the system is on the inside of the pipes and the water condensing on the coils from the moisture in the homes air and running out of the drain is on the outside of the pipes.
I would check the toilets, that is about the only place water could be getting into the drain without seeing it.
Firstly the noise is caused by rattling pipes which havent been secured down properly. secondly having low pressure after a while would indicate either air in the lines or your water pipes have started to clog up somewhere
no. repair or adjust your water level valve.
Electrolysis in plumbing affects the copper pipes used. If electrical wiring is installed too closely to copper water pipes, the electrical current running through the wiring charges to copper piping combined with the water and its properties causes electrolysis in the copper water pipes thereby weakening them.
