InFloor Radiant

Paul Rohrs_5

It's a pretty solid company in MN. They make a B pex as well as a Pex-A.

I do not use their tubing, but they make some electric infloor radiant kits that are dependable and affordable.

ever heard of?

Have you guys ever heard of the tubing manufacture called "In Floor?"

I had to do a small re-pipe today on an "In-Floor" system and found a lot of "crude" in the system. The tubing is almost like a white multi-core and the water that was purged out had what looked like traces of this tubing.

There was also a clogged zone-valve and relief valve that was clogged with a white hard substance.

Paul,

Any idea what the thick deposits and crude could be?

Sounds like...

a leak in the system somewhere and you are seeing the byproducts of same. Try shutting off the make up water and see if the pressure drops. DO NOT LEAVE IT OFF WITHOUT CONSTANT SUPERVISION.

I've seen

guys cut the tube with a hack saw and leave traces of the tube in the system.

Early InFloor tube was non barrier. How old is the system?

Also hot water heaters has an issue with disolving dip tubes a number of years back. A `white or light blue plastic residue was the byproduct. Is the system connected to a tank style water heater?

Sludge is generally from O2 getting in, or as Mark said constant make up water being added.

water heaters

If this system is tied to a Rheem water heater they had dip tubes that would break down and peices would float around in the system cloging any orfice

The system is about 8 years old and it is tied to a Bradford White direct vent hot-water heater. The substance almost reminds me of the glass coating inside the tank!

Process of elimination

First I would remove the dip tube. That may be the easiest first step. That is about the vintage tank that may have had a bad dip tube. As I recall the Precision recall involved ten's of thousands of tanks of various brands.

I believe the manufacture can look up the date and serial code of the tank to confirm that.

If you remove it and it is crumbling away, then a good power flush will be needed to get all the pieces out.

As long as you are in the neighborhood, remove the anode rod and see if it is deteriorated. Some water conditions would cause them to dissolve.

If this is an open system (I hope not) you could be seeing the silicas that gel up inside the tank from hard water conditions.
