Weird Water Heater Tank Connection?...


can anyone tell me if you ever seen a water heater gas line to be connected to the hole where the pressure valve was, and then from the place where the pressure valve its supposed to be another flex gas line comes out to feed the ingnitor?



I never seen this way for a water heater to be connected. A friend of mine told me that's the way it used to be?
The place where the pressure valve its supposed to be, has this "T" connection where the inlet and outlet gas lines are connected, and they both are hot to the touch due to the fact that they are in close contact to hot water.

The way I understand your situation...

With water at 50+ psi and gas at a maximum of 2 psi, seems like water would be forced into the gas line all the way back to the regulator and perhaps beyond.

And I bet all the gas pipe connections would leak like crazy with that pressure.

That can't be right.

This is a joke, right?

I am not a plumber but i think I know what you are talking about. My sister had this old copper core water heater (37yo heater and still working) in a house she bought and instead of your standard pressure relief valve it used a valve that shut the gas supply off if the temp got to high. The valve was where the current heaters and the pressure relief valve. I figured if the gas shuts off the water stops heating and expanding so the pressure goes down. Here is a link to one. http://www.westsidewholesale.com/aut...215_a_7c575034

Re: Weird Water Heater Tank Connection?...


Thats called a Watts 210-5 safety valve in case of high water temperature
it shuts off the gas supply to the heater there by preventing it from
blowing up
They are used in place of a regular t & p valve for a house on slap
when there is no way to run a proper drain pipe from the t & p

How can there not be a way to run the drain for a T&P? Here the WH is often in the garage and the T&P goes out the wall.

Re: Weird Water Heater Tank Connection?...


Yes but we don't all live in the same parts of the country !

while many houses in SO. CA. have their water heaters in a garage or
on the outside of the house,
Many also have in the center of the house,
Or like here in Houston, Texas many are in the attics so you can Imagine
what it must be like when they flood out !

I found that this way (that I described in the original post) it's not allowed in SANTA BARBARA constructions or plumbing installations. Somehow that's the way it's, but how safe it's..?- I do not know that.
I have only 10 years working as a general contractor in California, and this is something new to me, I still need to learn a lot more, always something new to learn.

This is the same house, as you can see in the video, the water is very bad. We figured that somehow the gas leaked into the tap water supply lines thus causing the water to poison.
Also, I tested the water for lead with one of those Home Depot's Lead test kits and it did shown contaminated water.

I was amazed at how easily it went through the floor joists, ceiling joists, and rafters.
