If this is a new installation, make sure the unit is feed with at least 208+ volts of electricity.
If it is an older tank, try turning up the temperature setting on both thermostats. Set the top one 10 degrees higher than the bottom. If there is now change in the water temperature after a day or two, replace both thermostats. While your at it, change both element as well. A complete universal electric water heater rebuild kit should only cost around $35.

The drain is a plastic valve, looks like a knob with a hose fitting coming out the middle of it. It should be about 1' above the bottom of the tank enclosure.
Be sure to turn the gas off before you drain the water and fill the tank before you relight it.

can you lit the pilot and if so will it stay lit

Vanguard... | Answered on Sep 24, 2009

If it is an electric water heater, there is no pilot light. You could have bad elements or bad thermostats. Be careful working on an electric water heater, as most use 208-220 volts!

If it is a gas water heater, it could be a bad thermocouple, ignitor, gas valve.

My advice to you is to call a qualified service company to come repair your water heater.

Your thermocouple is bad, that's why it won't stay lit. But you are in the right place. The thermocouple is located right in front of the pilot burner. It generaly pulls out and then you follow the copper tubing back to the valve, unscrew the fitting and it will pull out. Go to your local hardware store and purchase one about the same length and install it back in the same order. Good luck.

MUST be pitched IN (toward appliance). Otherwise ice will build up outside until it is blocked.

Change The Thermostat Cause If Your Getting Gas But The Water Heater Doesn't Detect The Heat It Will Close The Valve. When Lighting You Hold The Button Down For About 30 seconds so the thermostat will detect flame and stay lit. Check To Make Sure The Thermostat Is Where It Should Be. Heres A Picture Of What It Will Look Like.

You Can Replace Them If Need Be Will Be Available At Sears Or Home Depot. Also They May Sell Them At other Local Hard Ware Stores.

The pipes coming out of the heater normally do not unscrew so that should not be what you are trying to unscrew. The connections to these pipes do unscrew and a 12" or larger wrench should be able to break the bond on the pipe threads and unscrew. Sometimes it helps to apply some WD-40 or any penetrating oil and then tap on the nuts with a hammer to help break up any corrosion or other bonding material that is holding the nuts.
Go to the manufacturer's website and enter your model number and click on "Support" and there should be a FAQ's, Owners Manual or other support options for you. Otherwise the website may have a "Contact" phone number to call or a way to Chat online.

Make sure you have 1 square inch per 2000btu's (rating on the water heater) of fresh air for proper combustion

Hello abcd. Vanguard appears to be manufactured by Rjheem
Rheem promotes that their products require specialized 'resistorized' elements or 'all copper' elements to portion larger brand-specific sales in their pocket and for no other reason.

1) Buy 3600 watt element. Nothing special needed:
Copy following link to identify type of element:

2) March 2013: Add a comment and describe the water heater and the element.
