munchkin condensate trap leak

Bob_38

I just had a Munchkin T80M installed about two weeks ago. The installers were having trouble with a leak from the top of the condensate trap (right where the white rubber tube connects to the bottom of the munchkin heat exchanger). They thought the problem was that the white condensate tube might be angled too high, so they tried to adjust it lower and that seemed to be okay. Or at least when it was leaking, if they pressed down on the tube, the condensate would flow out into the pump and the leak from the base of the unit would seem to stop.

However, I just went down to check on the unit for the first time in a week and noticed a pretty decent puddle on the floor under the unit. I also noticed that the bottom of the munchkin was flooded and that the insulation around the bottom of the heat exchanger was completely soaked. I'm having difficulty observing the condensate leak right now -- I tried setting the thermostats on high to cause the unit to run, but I'm not getting much condensate at the moment -- I confess I don't really understand what exactly I need to do to maximize the likelihood of condensate generation.

So I plan to call HTP up tomorrow, and the installer will come over to look at it as well. But in the meantime, has anyone else experienced this kind of problem? Is there any lasting damage caused by the puddling of water at the bottom of the unit? Is this problem likely just an adjustment of the condensate trap tube, or is it more likely that there's a leak around the actual heat exchanger?

Im having the same trouble with a T80 I installed about two weeks ago.

One thing to check is the barbed fitting for the condensate drain. The gray plastic fitting has a small hole in the middle of the barbed fitting. The hole must be in the 12 o clock position. It is a vent.

But.... I did that and I still have a small leak at the bottom of the heat exchanger which soaks the yellow and gray insulation.

HTP is on it , they have been very good.

BTW, I dont think mine is a condensate leak. Im losing system pressure.

Ill update this when I figure it out.

we found a leak today also,

it was from a sensor threaded connection..my partner tightened it up a full turn..doesn't the factory test these things?

Leak

I had the same thing on a t80. The first trap had a pinch hole in it that I noticed on the install, htp sent me a new one and it work great for a week, then I noticed a puddle. I removed and reinstalled with great care to get the clamps in proper position. It's been fine since then. I would say that the rubber drain seemed to be a very loose fit, kind of like a howloween mask type rubber and it has to be positioned just right or it will leak.

I like this boiler though. When matched to the right load it just purrs along like cruise control.

Shipping is hard on these units, extra care in packaging would pay off in less damaged goods and callbacks.

Drain trouble

Again?

There is a funny looking hole in the back. Read the instructions. I'm quite sure that if everyone would take the time and read them, we would have never any more M-problems.

Right?

Correct you are

My boss is getting fed up with Munchkin service calls. Funny thing is, thet're all new installs by our company. You know what else is funny ? My partner and I don't have any calls on our Munchkin installs. The difference, we read and still read the install manual, just in case there are any new updates.

I am not the installer of this, so I confess that I didn't read the installation manual thoroughly.

Can you be a little more specific about the "funny looking hole" and if appropriate, where this is referenced in the instruction manual? This information would be helpful for me to make sure that my installer is doing the right thing.

Thanks

Well it looks like the drain hose wasn't seated snugly enough at the top -- fixing that fixed one leak...

But, they also found leaks around the high-limit sensor which required a full rotation, and they found a leak around the relief valve which also required a full turn.

So either you're getting lucky and getting equipment that was properly assembled at the HTP plant, or you're going to extra lengths to check on all these fittings when you do your installs. If it's the latter case, then maybe HTP should add a note to their installation manual saying that all of these fittings need to be field tested by the installer.

There is a small hole on the barbed fitting. It is located in the middle between the barbs. You must face this up.


UPDATE:

My T80 is now dry. Its been dry for 2 days. I think one of two things happened:

1)there may be a system leak like from some threaded connection. It may now be plugged up by all of the sediment in the system.(I havent flushed the system with the Rhomar product yet)

OR

2) tHE LEAK WAS FROM THE IMPROPERLY INSTALLED CONDENSATE DRAIN, WHICH WAS BACKING UP AND SATURATED THE INSULATION IN THE BOTTOM of the unit. This, however would mean that it took a week to drip all of the condensate out of the insulation.
