Yes...you have to manually fill the tank...and yes you have to source distilled water and potassium bicarbonate....but the end result is you won't have the corrosion issues you have experienced. I am not sure of your set up placement. I am fortunate to have my Sync on a counter with real high ceilings and no obstruction to the water tank. Also, I am wondering what effect your water has to your plumbing....and other appliances.

Hey,

Curious about your two boilers rusting through.

AFAIK the boilers are welded SS316 and seem rusted through on the edges, where its welded (with a generic SS304 filler usually).

Considering your water isn't great, I still find it hard to believe it's only that. And the galvanic corrosion between copper, stainless & steel is negligible imo.

Assuming you have the machine plugged into a grounded socket
Could you measure the voltage between the socket-ground and actual 'ground'. Here probably a water line, tap, heating system or something would be a good bet. Or your machine for consistency (while its not plugged in, ofcourse)

This should be 0v. However, it could be 1-3v. Causing something not much unlike galvanic corrosion.

Not that (& rubber soles) you as a person could build up a static charge of 100v easily. So probe something well conducting to mother earth.

I do have the machine plugged into a WEMO programable timer so confirming ground was a good idea.

I didn't have access to a good actual ground, so I checked the the ground to hot and got 120v/Neutral to hot 120v / neutral to ground 0v.

I also did a continuity test from ground on plug to both boilers and circuit tested good.

Following the advice on the forum I check the grounding and now Ive replaced the BWT Bestmax with the iSpring RCC7AK reverse osmosis system with remineralization. System installation was very straightforward.



Water quality improved dramatically.



Thanks for all the good advise!

snjsanders Congratulations, looks great! Now maintenance focus moving down to the undersink space which is more reasonable and cost effective

Note you can try every socket in the house (with ground), theyre all connected together.

But yeah, 0v is 0v!

ECM is on a WEMO timer and is on for 4hrs a day

Added a Calcite Filter Cartridge from Chris's Coffee to the iSpring RCC7AC and my numbers improved significantly.
The Calcite Filter Cartridge doubled the Total hardness and Alkalinity and added 50% to the TDS values.
