Sludge buildup in monoflow system

Harold Engstrom

My wife and I have been stuggling for 2 years now with our monoflow system (3 loops, burnham revolution boiler): we constantly have to bleed the system and when I upgraded the taco circulators from 1/25 HP 007 models to 1/8 HP 0011 models, I noticed the old circulators and surrounding pipes were choked with rusty sludge.

How do I remove this sludge? Burnham recommended TSP.

Also, how do I find a contractor that knows what they are doing? We have had 3 come in and each scratched their heads and left without solving our problem?

Thanks,

One other thought

Just curious here, it definately sound's like you have a water issue and need to get the system flushed. But do you have issue's with your domestic water? I am just wondering if you need to get the system flushed and then bring in boiler water. Sounds like you have some heavy mineral deposit's in there.

sludge build up

check the entire system for leak. some time ago, we kept on loosing circulaters. multi zoned.discovered rust deposits on the impellers. turned out there was a leak in a indirect pool heater, located in a different area of the building.the result, the make up water brought in more minerals[ sludge ], and not to mention air [ the O2 in H2O]

Leak

Air and rust....Hmm. Do you have any pipes that go under a slab? They could be leaking ..... which brings in fresh water and air .It would turn your system to junk....Rot it from the inside out.

Leak test.....Shut off the feed to the boiler and check for a pressure drop. A pressure drop indicates a leak.
