I am trying to understand my house hot water plumbing system and whether I have things set up correctly.
I thought I might have a problem with hot water loss as when we are away from home for some time, I shut off the hot water heating and this reduces my power usage from about $6 to $3 per day.
I have had a look up on my roof and there is no sign of water leaking out of the header pipe.
The tank is a Rheem low pressure cylinder dated 4/2001, but I don't understand all the valves, controls and settings.
I have labelled a photo.
1 Water drain... originally I thought this was a cold water feed
2 Drain valve... normally closed.
3 Pressure reducing valve.
4 Cold water feed shut off valve.
5 Cold water feed.
6 Anti-scald temperature regulator.
7 Hot water from top of cylinder.
8 Lower temperature water feed to sinks and shower, etc.
9 Low pressure cold water.
10 Cold water shut off valve to hot water cylinder.
11 Cold water into bottom of cylinder.
Any updates would be most welcome...
