1) I believe you can immediately elbow the PVC pipe.
There is a limit for how many elbows can be used between blower and termination, and limit is determined by diameter of PVC pipe.

2) Copy following link for venting resources and typical Rheem and Richmond power vent manuals, and diameter-elbow pdf from Bradford White.

3) Richmond is Rheem. Product manual will show specifications for venting.
Product warranty is voided if installation does not follow specifications shown in manual.

Hi,
The one with the pipe going to the bottom is the cold...cold water goes in on the bottom and the hot comes off of the top...hot water is lighter then cold water and rises to the top...

If water is leaking from a pipe. then replace or repair the pipe or fitting. If the leak is coming from the unit itself, then replace the unit. Hope this helps.

Yes manfactured on or around 1999.

the hot water tank may be filled with scale buildup on the inside. drain a few gallons out of tank until the water runs clear. it is best to drain out water heater at least 2 times a year.

Is it a new unit? If so, the safety mechanism may has tripped. If it is a GE built be Rheem, the safety device is a one time device - you have to replace the water heater. Check to maek sure you don't having a venting problem.
