SOURCE: dripping from drain spout

If you are refering to the "Dripping coming from the preasure tempature valve,Then just turn off the valve where the water goes into the heater and open the P/T valve with a bucket below it draining only emought water to get below the level where it reaches.     Normally the drain valves are plastic with a Male hosebib attached.  Attach a  garden hose to the rain and run it out to a point lower that the vaslve in order for gravity to drain the tank.The valve opens counter clock wise. If the valve is stuck or does not drain,and you have a foor drain handy,remove the whole valve and replace it with a boiler drain valve.  If The tank is located below the drain level then you will have to either pump or carry the drain water to the higher level.     Replace the P/T valve  and reinstall the associated associated piping. I would use tefelon tape on the P/T pipe theads.    You may have to open a hot water faucet in order for the air to replace the water in the tank ,in order to drain.

SOURCE: My Rheem hot water heater stopped putting out hot

If you are not familiar with the element, I would get someone that is familiar with one and have them do it. It's not something I would recommend you do based on your question. There's electrical, pressurized water tank, and a whole lot of water that may cause you to have a worse bad day.

SOURCE: Not heating water hot enough or as much water.

You probably have a bad heating element. Probably the upper element.

Can i convert a Rheem ECO 180DVP (LP gas unit) to a natural gas unit ?


Rheem water heaters should not be converted from propane to natural gas. The burners have been optimized for the rated gas and will not work as well after conversion. (Unlike ranges where the gas/air flow ratios can be adjusted when the burner orifices and regulator are swapped, the water heater doesn't have that option.)

I wish I had better news for you. I recommend you get a new water heater for the LNG service; it will be safer and more efficient.

How do I convert my rheem water heater from lp to natural gas model#21vp40-1p


Call Rheem
Generally the company does not support changing type of gas since propane burns much hotter and has more pressure than natural gas.
You need different gas control valve, and need cast iron burner and orifice than matches that specific gas control valve.

Rheem 300170 HWS service manual


1) Rheem does not post service manuals.
Call Rheem and ask why, since the other big manufacturers, AO Smith and Bradford White do post service manuals.

2) You need new propane gas control valve, and matching combustion parts to fit existing tank.
http://waterheatertimer.org/pdf/Rheem-Water-Heater-parts-catalog.pdf
http://waterheatertimer.org/images/IMG_1826-LP-burner-450.jpg

3) Rheem does not recommend changing gas type, especially from natural gas to LPG.
LPG is higher pressure, and burns much hotter and requires cast iron burner, unlike the lighter-weight metal used for Natural gas burner.
The manifold tube and thermocouple must match the gas control valve, and gas-type and have correct thread for propane.
The combustion chamber and heat transfer surface can also be heavier metal for propane heaters.

Can the Rheem PTG2-42PVN be used with propane gas?


I believe PTG2-42PVN is natural gas.
Rheem site does not show that model number.
As a general rule, Rhemm does not recommend converting NG to LP and LP to NG

Sounds like you may have the wrong type gas going to this? Is this an LP gas or natural gas unit? will say on label. Natural gas units run only on natural gas ditto for LP. Could be issue with manifold pressure settings. Could be obstruction in exchanger or vent. Have a authorized technician check over

My new tankless WH stopped working. It gives hot water for about 15 sec, then starts flashing C7 12 or C2 11. How can I fix this, We had it for a month now & it worked before.


11 The Gas Shutoff Valve is not opened
completely.

12 Gas Service has been interrupted.
LP Gas is running low. (LP models only)

I think C7 is where the startup sequence ended...and then you get the error code

If less than a month old...contact your customer support
