kitec tubing failure

Brett O'Connor

Give me a call

Be happy to help in anyway. Very familiar with the system that you installed. Paul has my number. If this is designed with the 110 stats and constant circ. I would look towards this being a large player in the problem.

right on

that is what appears to be happening. but how can you do the fitting worng? if the fitting isn't leaking at install how can you tell if it is leaking within the fitting and infiltrating the pipe layers?

fill water sample came back clean, system water sample will be back soon thanks to rhomar.

kitec was on site yesterday. they need more time

electrolisis is my gut reaction

may be something to do with kitec connecting directly to the water heater. the first pipe to fail seems to be the 3/4 connection between hwh and hydro panel. other pipe people require meal pigtail at appliance.

Thanks

for the update. A company i sub for uses lots of Kitec so we are intersted.

oxidation is coming to light

when the pipe is split apart white powder falls all over. the question is the oxidation causing the delamination or is it the other way around?

mark_41

water sample came back clean

infact the water is so clean it looks like distilled water. maybe that's a problem?

I'm curious Brett

What effect (unwanted) would constant circ and/or 110V stats have on the Kitec? Are you saying the failure could be erosion based or stray current or both?

thanks

I have been hanging in here on this one a while now....

I am of the belife that you will find degradation around transition fittings...if so please tell all of us what the cause is... right now i belive it is of a two fold nature one Pilot error kinda deal the other has something to do with dissimilar metals as in like pizeio electrical effect i belive the term is migration and as i have always liked modern hippie terminology....Get my drift?

we have looked at install

and find nothing to beleive it is pilot error. use kitec fitting and tools, install is streight forward. dissimalar metals idea show no signs at transition fittings. fittings are all clean, pipe delamination is appairant at some pipe ends but not all. the water sample came back clean, so clean that the water is almost distilled quality. which may contribuate to the problem. all piping failed has been from same block at the project and the same batch of pipe from factory. could be some sort of defussion ox or chlor or hi temp w/constant recirc

Just a reminder

the clear water was from the fill water. I am waiting to test the system water. I expect it to be OK, but until it is tested the verdict is out.

Kitec tubing failure

Checking in with the ongoing investigation. If you have any pics. of the piping on this project I would very much like to see those. What are the kitec people saying?

Thanks in advance

mark_41

pictures are fortcoming will have tomorrow

no answer yet. kitec ask for 4-6 weeks
2 weeks ago

S. Ebels

The reasoning that I was trying to convey deals with constant circulation and water temperature. Some PEX manufacurers not to be named have clames that have been re- adjusted from the findings that we have come across.

It looks as if this is not the issue.

Weezbo

I missed the ending of this thread...

so whatwas the final determination ?

mark_41

still nothing from kitec

they seem to be at a snails pace. pipe samples, water samples but nothing to report. all we know is the pipe failed

Kitec failure

Good luck,
We had a Kitec tubing failure on a job about two and a half years ago and still have not heard back from Kitec as to what the problem was. We had to replace the tubing with Wirsbo and have not used a single inch of Kitec since. Did not have any black spots but the tubing would delaminate at intervals with a new failure showing up about every three or four days.

Kitec failure

Had Kitec runs underground for hot and cold and recirc lines for potable water to bar area after about 5 years had to pull pex lines through the 3/4 kitec to keep system operating , or break up floor was only option . system had 5 different repairs done to it before running new lines , no black spots just pin holes in pipeing

Chuck Waters posted today ....

he was apparently oblivious to any concerne whatsoever in this specific matter....he did state however that in deed the company has a veritable spectrum of professionals working on some similar problem ....and that indeed there are plenty of round toits getting around to it.i Hate it when i am the last person to be made aware of a problem. by the time that happens the nails are being driven home on thecasket that is now slated to bury me in..i am fairly sure he read Dan's Blog and had just stopped by to see whats new in Dan's world.

coming from one involved in this mess

ipex should be thankful that the owner is a prince. over the holidays there was another failure. the owner is repairing with his own forces, can't ask for more than that.

rhomar... attn george

would you be willing to comment on the water samples sent to you?
