Heat pump water heater nipple.
Hey folks.
Does anyone know if this hot side of a Geospring water heater tube can be replaced?
Thanks in advance.

I'm happy to see that after 12 years this heat pump water heater is still going with the failure point being a nipple. So now according to the logic that I always see used against them, we now know that heat pump water heaters outlast every gas water heater.
(and I wish you good luck in getting the nipple fixed!)

Looks like part of the dip tube/ anode rod nipple has broken off in the tank?
That looks like a copper to female adapter screwed on the top 1/2 of the nipple, them rest may be in the tank?
Not such an easy place to work, unfortunately. It may involve a small chisel and a 3/4 pipe tap.

Hi, Is that the hot or cold side? Also, there is a plastic cap down on top of the tank. Is that covering an anode? Replacing the pipe may not bo so difficult as long as you get the replacement beforehand. Also, the copper to steel connection should be redone with something that doesn't mix metals. I'd probably use a stainless flex connector that has true dielectrics built in to the ends.

That looks like the remnants of a dielectric nipple. Possibly a leak on the adapter has corroded it away. Maybe with some electrolysis involved?
There are some dip tubes that combine the anode rod into one piece, or have a vacuum breaker hole on top of the dip tube

I see now, (looking at this on my computer instead of phone 😏) That's blue plastic visible where the steel has left. It's likely caused by the copper to steel connection. Getting the nipple out will be harder because i has to be grabbed low down… maybe a basin wrench with a crescent on the square shaft?

or one of those basin wrenches with the socket drive hole.

Im at a loss for unscrewing the nipple. I'm betting on it not moving. Haha

shove a rod or bolt or pipe just slightly smaller than the id inside it first so it doesn't collapse

Something like this might do it:
might be a more economical or used version somewhere. an inside pipe wrench might work too. might be coming out in pieces by cutting it close to the tank then cutting 2 slots almost to the threads and knocking out the piece in between with a caping chisel (there are some very thin reciprocating saw blades you can put in an mini hacksaw or jab saw and use to make the cuts)

Do they really have a bad reputation? They seem awesome minus the higher chance of mechanical failure from being a more complex design. Especially if you keep it well maintained...

anything refrigeration made in about the past 20 years has a high failure rate due to leakage of the sealed system.

They are pretty great in my opinion. A lot of folks in this forum don't trust them even while admitting that a brand new gas water heater life expectancy is apparently now down to like 7 years.

do you have data for that “high failure rate”?

I believe it's still 10, with some lasting longer, some lasting a little less etc.
Some people get 20-30 years from one apparently.

Some people say 10, some people said 7, it's all just opinion with no real data I admit. Just like the opinions about heat pump water heaters.

I have a stack of 4 dehumidifiers that each lasted 1-3 years. well technically the 4th is still hanging from my basement ceiling rather than in the stack. i need to contact aprilaire about that before the warranty is up. at least the aprilaire one is in a steel case so the compressor isn't likely to set the cabinet on fire after it loses the cooling from the refrigerant.

my last one was 18 years, the one before that was over 20 and i replaced it before it leaked to get a power vent version to get rid of the chimney.

a good group of anecdotes to add to the pile!

My dad has gone through a good 3 or 4 dehumidifiers recently as well as my boss. I'm waiting to join the disposable club as well unless I can find a good used one.
No, this isn't an anecdote, it's a fact there's a huge problem. We're all saving the planet by dumping all of the refrigerant into the atmosphere and the plastic and equipment into the landfills.
Does this apply to HPWH? No clue.

Respectfully, unless you know how many are failing vs how many are sold it is exactly an anecdote. The companies know but will never say

if i add an access valve and put something like leak freeze in it, it will retain refrigerant through the cooling season as long as the stop leak is circulating and sealing the new leak but it leaks out over the off season after the stop leak stops circulating. the fact that most of the ones made by greer were recalled because they tend to catch the cabinet on fire after they lose their charge is also concerning. someone i went to high school with had a house fire that was started by a chinese dehumidifier.

When multiple people tell you multiple brands of units all lost their charge in a year or two, it's a pretty bad sign.
They're garbage, and you know me, that's not the fault of the technology, we've known how to make them last 100 years for a long, long, long time.
Wonder if you can find a HPWH built like a monitor top……………..

I tend to believe you, which just goes to show I can't even trust myself haha
I'll be sure to let you all know when my HPWH fails. So far it is on track to go as long as a monitor top 😅
I hope the OP got his nipple changed out!

Hi Dustin, My word for you today is not "plastics". It is anodes! 😇

My plumber buddy told me that with dielectrics on a water heater they last a long time. The last one at my house was a 10 year gas fired and at 15 it was still going. I tossed it when I changed the boiler and did an indirect.
I owned that house 34 years. The wh that was their failed. I think I changed it 3 time so that's about 10years each
