Am I stupid, or should I have been an engineer?

a tee and a boiler drain on the cold water side of the domestic water inlet.
Hook a hose to that and the dip tube will siphon the water from the tank. This is because that heater is a tank in tank design and the inner tank need to move.... so no bottom drain.

BTW... hope you didn't just chuck that tank.... it's covered by a lifetime warranty and I have gotten the only one that ever failed covered even though I didn't install it and the jerk that did had the domestic water going into the outter tank instead of the inner one.....

That's customer service......standby your product even when it's not your fault....

Went to replace this tank on Friday, drained boiler side but couldn't find drain for hot water. Luckily it was a walkout basement so we dollyed out and tipped over.Couldn't find any place a drain should have gone. Am I missing something ?

It is a siphon drain.

IDWH Drain

It was not practical to design a bottom drain on these units. The inner tank "hangs" from the top and flexes as it heats up/cools down ... a fixed drain on the bottom would have limited the flexure. The manual that came w/ the unit shows how to drain the unit.

Whatta ya mean ?

I thought I got the only one to ever leak

Maybe I got the only one to ever leak upon installation ?

You're right though, they stand behind their products.

They sure do

My neighbor is on his 4th Phase 3 . Triangle Tube only asked for the 1st tank back . They never asked for a water sample or pressure reading , they just keep giving him new tanks . Now that is customer service .

If there isn't a drain on the cold inlet , we stick a piece of 1/2 inch soft copper into the tank and pump it out . The siphon trick works pretty good , you can get almost all the water out of the domestic side of the tank .

tank drain

Thanks for the help, good to know fof next time (there was a drain on inlet side--- didn't make any sense to me), of course no paperwork around and we never installed any of these.

An air compressors

works well, also. Great for any tank to drain them quickly, especially ones with limed up drain cocks!.

For that style of tank air on the hot side and attach a hose to the cold (dip tube) side to blast 'er dry.

Much quicker than the siphon method

Just out of curiousity Alan, why did the tank fail?

Better, FASTER...BIGGER!!!

HR, I used to have a cylinder of liquid nitrogen that I purchased for freezing water lines. We hooked it up to a 2,000 gallon horizontal hot water tank we were draining to get the insides lined in stone. We emptied the tank in 30 minutes. Shocked me.

One time, at a house I occupied with a bunch of guys when I was between wives, our water pressure was so bad that you had to move the sprinkler 6 times just to water the measly front lawn. And god forbid if you tried to take a shower on the second floor with the lawn faucet on. I heard it suck air once...

So, after the city went down our street and replaced the main, our water pressure still sucked. So I got the wild idea to hook my nitrogen tank up to the sill cock and applie a "little back pressure" to see if we could back wash the service back into the main. I turned on the valve and counted to 5... No gurggle gurggle out of the DHW tank, so I opened the tank valve again for another 5 seconds. Still no gurggle. So I kick the valve wide open for 15 seconds. Pretty soon I hear yelling and screaming coming from the basement. SHUT IT OFF, SHUT IT OFFF!!!

I'd finally put enough pressure into it to the point that it lifted the pressure relief valve on the DHW tank down stairs. Things reset and settled down. I opened a hot water faucet in the slop sink, and so much rust and crap came out that it plugged the already weak drain in the slop sink. After the rust quit flowing, I found that I could water the whole front yard with a wave sprinkler in one shot. About a year later, the service failed at a connection between the galvanized coming into the house, and the lead service serving it...

(Bumper sticker seen in RRCC parking lot) If it doesn't work, force it. If it breaks, it probably needed replacing any way... RIGHT??

Ya gotta respect them gasses. The got a lot of power to them.

tank replacement

Kyle, we replaced the tank because it was leaking from the inner to the outer tank.The reason we found it was the boiler kept leaking from the relief valve.After changing numerous other parts we realized this was the cause. pressurized it with air back at the shop on the domestic side and it leaked air into the outer tank. The boiler side was antifreezed, and from what I understand this voids the warranty.(could be mistaken)

PRESSURE and

gravity are two things that always amaze Great idea.

Perhaps a hellium charge, instead if nitrogen, would drain the tank quickly and make it very easy to haul up the stairs
