Entran3 problem

kevin coppinger_4

a whlie back I posted a note for help with a clogged line of heatway enran 3..it has been in service 9 years. There are 200' loops one works 1 does not..plugged w/ what appearsto be iron particles(magnetic) I tried the compresses air trick,110 psi, helped at first then nothing...flushed out other line w/ rhomar 9100...helped but the other line is behind tile....any other hints? anyone ever used a 1/8" plastic icemaker tube as a snake? kpc

If you could get ice maker line into there

why not pressurize the line and make a mini-jetter out of it, perhaps 100psi spraying against the gunk to loosen it, even put on a nozzle of sorts to cut at the blockage!!

Tough one

If the 100 psi didn't dislodge it, I doubt the icemaker line with the same pressure would make a difference. Since you would have leakage around the insertion point you would have less pressure.

Maybe a vacumn on a 1/8" line would be better. At least you are removing instead of pushing

I suspect you would only get around 3 or 4 bends before you couldn't push any more catheter, however.


Since you are looking at maybe abandoning them why not try a HIGH pressure. Got acess to a pressure washer? Connect one with a pressure regulator and try 150, 175, 250...?

My info shows a 750 psi burst rating for the E-3. Not sure what type of fitting you will need. Possibly a hydraulic hose type of crimp.

Be careful with high pressure safety glasses a must.

Need to find out why you have that build up in the first place!

the water quality was not pristene.....

from the well and the HO wanted to add in glycol into the system...against my advice... everything worked ok until last winter. The glycol was in the system only 12 mo. before I drained it out. Not sure that that helped matters. kpc

The gunk you describe

usually comes from the ferrous components in the system, pumps, expansion tanks, boiler sections, being attacked by the fluid in the system. not generally from the well water. Unless you have an iron bacteria in the well!

If you haven't flushed away all the original water (fluid) check the ph, etc. i'd be willing to bet the glycol has gone acidic and is attacking the ferrous.

Or a leak that allows lots of fresh (oxygenated) water into the system to support corrosion.

The addition of glycol, if it was inhibited hydronic glycol, really should have helped conditions inside since the inhibitor package is "brewed" for that job.

If you get things flowing adain a good strong Rhomar cleaned, flush, and haul DM water to the job and a dose of Rhomar conditioner.

But be sure the system holds pressure!

Good luck with the clean out. This is starting to show up on the original PB/ cast boiler systems also. Plugging the 1/2 PB like it was cement poured into the loops!
