TPR Discharge pipe reduction
I came across this water tank today. When I looked at the tpr valve I snapped a picture and moved on just thinking it was incorrect. Now when I look at the picture, I don't see a reduction fitting at the top of the tank. I have never seen a 1/2 inch fitting (in the body of the tank) for a tpr valve. I see a reduction in pipe size after the valve quite often but I have never seen a reduction between the tank and the valve. Am I missing something?

Re: TPR Discharge pipe reduction
I would agree with Fritz. Could that be where the sacrificial anode rod goes?

Re: TPR Discharge pipe reduction
That's what I'm thinking too, and that this particular water heater is like some I've side, side T&P *only*, no top opening for the T&P (most tanks with a side T&P opening have that as an "alternate" opening, with the preferred location being in the top of the tank, but, I've seen a couple of tanks in the past which *only had* the side opening for the T&P).
Of course, if that is for the anode rod, that tank is probably gone now any way.

Re: TPR Discharge pipe reduction
Good call. I now know to look elsewhere on the tank for another fitting. You learn something everyday in this business.

Re: TPR Discharge pipe reduction
How old is that tank? I haven't seen that Harvest Gold color in ages!

Interesting call on the color Scott. I was thinking Gulden's Mustard.

Re: TPR Discharge pipe reduction
It looks like a modern 3/4 inch valve in an older tank with a 1/2 inch opening.

Re: TPR Discharge pipe reduction
Temp probe may be too short to be effective as well. From the Watts site:
"Alternate" ONLY when the tappings are not provided:
Use standard or extra length extension thermostat which permits the end of the thermostat to extend into the top 6" of the tank.
For Heaters with Direct Top Tapping:
Always use an extension type thermostat T&P relief valve which permits the end of the thermostat to extend into the top 6" of the tank.
