On the natural gas connection, which type of sealant should I use on thread?

So basically I am asking best way to seal the threads coming from the black iron pipe to the water heater itself. Best type of line between the two as well? Thanks
Asked by: scotta
On pipe threads, use a thread sealer that states it is compatible with gas systems. You can use paste thread sealer, or teflon tape that is compatible with gas (usually yellow tape instead of white). Do not use any thread sealer on flare fittings, and tighten them just enough to get a good seal. You MUST test for leaks after pressurizing the system and before introducing a flame to the vicinity. Easiest way to do this for DYI is by swabbing each connection with a mixture of dish detergent and water. Wait for several minutes to see if bubbles grow.

My water heater is located outside. Can I use this model outside inside a covering?

My water heater is located outside. Can I use this model outside inside a covering?
Asked by: Cris
This water heater can be used "outside" if it is in an enclosure that protects it adequately, Adequate protection includes keeping the base of the water heater above ground and dry, and having the structure strong enough to support the weight of the heater PLUS the full amount of water, 30, 40, or 50 gallons, depending on the size. The enclosure must also include adequate ventilation as described in the installation directions. In addition there must be an adequate means of makeup combustion air available.You may need to contact the manufacturer for that information. In addition, an outside water heater may freeze and be damaged if it is not operative during freezing weather. So it is very important to keep it operating when the weather is cold. Outside heaters typically suffer freezing damage when a resident moves out and stops paying the gas bill, resulting in a gas shutoff. The tank will freeze and burst but the damage will not be apparent until the ice melts.

Performance Plus 40 Gal. Tall 9 Year 40,000 BTU High Efficiency Natural Gas Water Heater is rated 4.6 out of 5 by 1534.

Couldn't return it to Home Depot as the installer was on-site and I needed it installed that day. I called Rheem and registered a complaint and they assured me the location and depth of the damage would not affect the operation of the unit. Luckily, the damage was on the top backside of the unit and not readily noticeable, so it was installed. I'll call Home Depot and negotiate a credit for the damage.

I knew very little about water heaters, and was able to research almost everything I needed on the Home Depot site. I replaced the water heater, the expansion tank, the venting pipe and ended up also replacing the water pressure regulator to the home. It took me a couple of trips to home depot as i was learning about plumbing but i was able to research on line and order the water heater and pick it up in the store. This is a very good unit, i read the reviews and researched an am happy with it.

Installation was fairly easy except the old heater was a few inches shorter and the plumber neglected to use a union, so I had to cut the pipes. Suggest the use of flexible stainless steel hose Homedepot SKU #1001555703 to speed connection. Liked the easy pilot light ignitor and flashing LED.

Rated 5 out of 5 by from Superior Hot Water Heater I chose this model over the most expensive model because the warranty and quality is excellent and I didn't see $125 more value in the top model. I did replace the plastic drain faucet with a brass one. (I've had trouble with the plastic ones leaking and it's much easier to replace it when the tank is new plus it was only $7.00). The one thing that surprized me is that this tank is the same capacity as my original but over 6" taller and 1" wider than my original. The insulation and design is much better than my original. I really like the convenient lighting and control system. It too is superior to anything I've had in the past. I HIGHLY RECOMMEND this unit.

My brother in law helped me replace this one for a blown out fat body 40 gallon heater with the same specs. It went in fine and the installation is nice and clean and looks and works great. I especially like the gas valve setup for starting and to keep an eye on the pilot (it blinks a blue light periodically to show you the pilot light is still lit - no battery so I guess the LED works off the thermocouple generated electricity). I give it my best rating (2nd water heater I've replaced myself or with help in two houses).

I'm 65 went to Home Depot,picked up this water heater,went ti install(hired someone)and there was a big dent on the side.Took the heater back,replaced,hired the guy again,after all the hook ups,the pilot would not lite.Called the emergency # ,explained the problem,they said it was the ignitor inside the heater,and since it was the holidays,I would have to wait the next week for the part.Received the part,again called the guy to install it,and finally it worked.It was 5 days without hot water............total disgrace,never buy a Rheem or purchase an appliance again from Home Depot!!!

This weekend I replaced my 10 yr old Kenmore Water Miser 9 50 gallon water heater with the new Rheem Performance Plus 40 gallon unit (regulations have changed so sizing is different!). Anyway, after reading many reviews on the offerings from Home Depot & Lowes, the Rheem offerings were a clear standout. After opening the box when I got home I can see why. Installation was a breeze and the instructions were clear and easy. Highly suggest this water heater for those of you who are looking! Ps, I replaced my previously soldered emergency drain with a flex hose with "shark bite" fitting - also highly recommended.
