Hi,

As per my photos below, I've just moved into a new house, and I'm still trying to figure out a few things, especially the water pump :-)

I have a few questions that I hope someone can help with:

01 - The pump seems to kick in (make a lot of noise), every 20 mins, which is very frustrating... I presume these are designed to be left on 24/7?

02 - I have to turn it off at night (red light switch in photo) as it keeps me awake... is this likely to damage the pump?

03 - The hot water seems somewhat dirty at first when I turn it on and I need to let it run for a few minutes. Any ideas why this could be?

04 - Any suggestions or recommendations are greatly appreciated.
