Easy Purchase

I purchased this unit to replace my 11-year old A.O. Smith ProMax water heater that had a slow leak. The ground shipping took 3-weeks to deliver; however, it only took 3-hrs from unpacking to installation in an attic before I had nice crispy clean hot water. The order process was so easy and delivery to my home was a plus. I'm looking forward to getting another 6+ years from this new A.O. Smith water heater.

I would not recommend

I have had to have it repaired twice to keep the pilot light going. Now it will not stay lit again. The cost of repairs every year or two is bad enough, but the inconvenience is worse. You never know it you will have hot water when you get up. I wish I had never got this heater.

Didn't last two years

After about 16 months we had problem with rust in the hot water. Flushing it produced a brown mud coming from the drain. Two months later the bottom of the tank ruptured and flooded the garage.

Walk-in Bathtub

We had a walk-in bathtub installed, and our 40-gallon heater didn't do the job, so we bought this one and had a hot water booster installed as well. So far, it has done the job for which we got it. There isn't a whole lot you can say in glaring terms about a water heater, other than it does its job.

A. O. Smith 50 Gal. ProMax Gas Water Hea

This is a great water heater. I am replacing the exact model which was installed in my new house 14 years ago. It was still running perfectly but two external valves connected to my A/C had rusted and instead of replacing the valves I decided to replace the whole unit. I never had a problem with it and no telling how long it would have lasted.

Nice unit

Website details were 100% accurate and was certain I was buying a unit that would work in my location. This unit replaced my older smaller AO Smith unit that lasted several years longer than the expected service life. Also able to operate this unit in the low temp setting with ample hot water.

Yes, the heater should operate correctly at 7500ft. Above 7700 feet the burner will require modification from the installer.

Q: How to drain 50 gallon promax

Asked by Tom 13 years ago

Add your answer

* Required Field
-

Hook a garden hose to the hose bib on the bottom side of the tank and place the other end outside or into a drain. Turn the thermostat to the off position. Turn the water off to the unit. Open a hot water faucet as far away from the unit as possible and leave it open. Open the release valve on the upper side and then open the hose bib valve to the right of the thermostat. It will take a while so be patient. Make sure your hose is flowing downhill or buy a small pump that connects to your drill and pump it out if you don't want to wait. There about $10 at Home Depot. After it's empty, I turn the water back on for a few minutes to flush out any loose left overs. Then shut the water off again and reverse what I did in the beginning except don't light the water heater yet and, I leave the hot water faucet open AND I open the cold water faucet at the same time. This lets the trapped air bubbles escape and prevents the pipes from knocking when the water is turned on and off. After you don't hear any more air escaping, close the hot and cold faucet and let the water heater fill up. You can light the water heater again anytime after you close the faucets. After the water stops running into it, open the hot and cold faucets for about 30 seconds then close again. Give it an hour or so and your water should be hot and running clear from the faucet. If it's not clear, you'll need to get a special cleaner to loosen the scale and redo the process.

Q: On the GCV-50-300 model it says to drain and flush the tank every 6 months.It tells you to hook a hose to the drain valve and then open the valve.This model has a tamper proof drain valve suggesting what? That you should not open it.There is no handle on the valve to open it but you can use a flat head screw driver to open the valve. Is this the procedure you are supposed to use?

The drain valve on this unit can and should be used as needed. It is tamper-proof to prevent small children from using it.

Yes. This is the procedure. Beats having little mitts draining the tank when turning a knob during the course of their day's fun and learning. Beats flooding the house as most people do not connect the drain valve to a drain as a matter of course.

Q: The label on my tank states model # GCV 50 100, is this the same as model GCV 50?

The 100 is the series number. A.O. Smith makes minor changes in design every several years, and current natural gas models are Series 300.

Q: I have a 50gal ProMax, but I can't tell if it is a 6yr or 10yr warranty model. Where is the warranty listed on the water heater?

Asked by Mark 14 years ago

The GCV units have a six-year warranty. XCV models have a ten-year warranty. The model number should be listed either on the water heater itself, or on the original invoice (if you still have it).

Q: I own a 7-yr. old pro max gcv-50 and it drains very slowly and has begun to leak regularly through the relief valve. Is this indicative of imminent failure? Is it servicable, or do I need to replace it?

Asked by 15 years ago

If you have an expansion tank on the system, the tank may need to be replaced. Another possibility is that the relief valve has a bad seal and needs to be replaced.

Q: Seem to be running out of hot water sooner and is getting worse. Could it be a build up of calcium and such so it is not filling up the full 50 gallons? We use to be able to fill the bathtub and then shower right after but now we have to wait quite a long time before we have hot water to shower

Asked by waukesha32 15 years ago

It sounds to us as if you may have calcium built-up on the bottom of the tank that is not allowing the burner to heat the water as rapidly as it used too.
