Hi,

The drain valve can always be replaced so you can drain that with no worries....after it is empty open and clsoe the cold water valve to flush more...

As far as being large enough... that depends...

If you have a teenager like I do that takes 40 min showers in steaming hot water... no....
If you are running more then one shower at a time... then probably not...

The other thing that could have happened is that the dip tube for the cold water inlet has broken off or disintergrated...that happens...
Usually you will then get cold water and the gas valve will not yet have kicked on the burner, because the cold water is not going to the bottom...

If it is a new install... check thet the supply and return are hooked up correctly...

thermostat is gas vavle may also be bad, but not too likely...

Before calling service technician, open following links for troubleshoot resources including error codes and rheem chat, and typical scheduled maintenance:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

Error 76 can mean communication failure between tankless and remote control, which can include bad remote control, bad wire, bad wiring connector, or PC board failure.
Disconnect remote control and see if tankless will work.

Error C8 76 can mean PC board failure.
Contact Rheem and/or service technician.

I have a recently installed richmond water heater. When the shower is running and someone turns the faucet on in the kitchen the water gets drastically colder in the shower. We didnt have that problem with...

Which type Richmond water heater?
Is this a tankless water heater or tank-type?

Tankless are notorious for 'cold water sandwich' under exact conditions you describe. You might need tankless with larger BTU burner.
Don't install a tankless.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

If you have tank-type water heater, then I suspect a clog in the hot water line, or single-handle faucet cartridge in show is going bad.
Same problems can contribute to tankless problems.

I have a model number 101160 manufactured in 1994. When showering I am using LESS cold water to maintain a reasonable showering temperature. If a tempeature adjustment is required, how do I adjust the...

Water heaters by Rheem have not changed that much over the years. the link below will give you some good information about electric water heaters in general. As water heaters age, the heating element will lose efficiency due to deposits and general build-up of minerals in the tank. Turning up the temp may not be a good idea since the problem is actually caused by a coating on the element. Also make sure that cold water is not bleeding into shower valves thru other single lever faucets. While shower is running, listen to and feel the water lines connected to sink faucets in other rooms for water transferring thru valve. You can actually hear water running at faucet while shower is on if faulty. If other vaucet valves are leaking thru, repair those first before you do anything to the water heater as that is cause of loss of hot water. Good luck.

I have a Rheem 40 gal. tank that is leaking water front the top where the vent stack is. It is pouring out. Can it be repaired?

A leaking water heater cannot be repaired, assuming it's the tank leaking and not nearby water pipe.
http://waterheatertimer.org/Water-heater-leaking.html

First thing is to protect your property from catastrophic tank failure where tank ruptures and water runs until it is shut off:
Tanks are under pressure when they are hot.
Close cold water shut-off located above tank.
Turn control knob to 'pilot' so pilot is lit but burner will not turn on.
Open hot side on tub for few moments to relieve tank pressure.

Now your property is safe.
You need a new water heater.
In mean time, gas water heater makes 41 gallons hot water per hour.
Shower used 5-9 gallons hot water.
Bath uses 10-15 gallons hot water.
You can turn on water heater for short stretches and limp by until you get a new heater.

Water is hot until you adjust the shower temperature to warm from hot, then heat unit shuts off and it is 100% cold. Shower head is low flow so wonder if the flow is below minimum for heater to fire?? Can...

These unit is design to operate at a specific flow rate and cannot be ajusted if you need to have a warm shower you will need to get a bath remote where you can turn down the temp whenever you need without disrupting the flow rate

Heater stops heating water

you have to much volume of water going thru the unit, did you size it properly by haow many baths and showers you have or did you just by the cheapest one,, there is a scale to go by run just one shower and see if it changes temp, with nothing else running,, a shower has 2.5 to 4.5 gal per min,, then you can also check to make sure it has the right size gas line 3/4 from the meter to the unit is required at a min of 2lbs of gas

Hot water taps and showers pressure very low cold taps ok

there is a little cap on the hot and cold side above the shut off valves, turn the water off at these valve and take the caps off there are filters in there clean them off and reinstall them that should take care of the problem, you might want to flush the tank while your at it hook a hose to the hot side connector and run it out side or to a sump pump then turn on the cold water and flush it out you can also reverse this procedure by doing it on the cold side
