I had set up roughly 500 feet and started my unit with the pressure regulator set near 600psi. When all that line pressurized it spiked the heat exchanger and the heat exchanger cracked but i was still able to finish the day some how. For those who are wondering why the pulsation dampener didn't help, its because the pulsation dampener was faulty. But even though that happened i still feel that a pulsation dampener is far superior to a high pressure hose whip off the pump to flex relief pressure spikes.

We don't have any spikes that's why there is a pressure regulator and an unloader. I think you had an over pressure situation or the exchanger had problems.

No, i set up about 300 feet of line that hadn't been used that had air in the lines. When i turned on the pump i felt it pressurize and come back to the machine and it blew at that point. But YES Mr clean and Joe cool it needed to be descaled. But from experience, i could have prevented it from busting if i backed off the pressure and eased the regulator up. My bad.

Bummer, Replacing heat exchangers is expensive. I have a Prochem Everest efi 06 last model with Nissan engine. I’m on my second round of HXs because I decided to cheap out and purchase 3 copper HX instead of 2 stainless steel and 1 copper HX. Does anyone have any info on where I can purchase ss HX. Thank you

Thank you. I called them this morning and I’m working on a few options since Sammy hasn’t fabricated a HX that small. But I’m hopeful.
