Have any of you guys encounter copper geothermal systems before?
I did a roof cleaning job last October where the home owner mentioned he had a copper geothermal system not to far from the house. We took extra precautions to neutralize any overspray and plant washed like crazy the area. Got a call today from the home owner saying the system went down back in December and that the manufacture said our process could have corroded a pipe in the ground. I'm supposed to meet the home owner next week to talk about it and wanted to hear if you guys have ever had a similar issue happen and how you resolved it.
No, Geothermal systems run under ground usually a few feet below the surface and are used to heat or cool water or air to a home or business. It uses the temperature of the earth as an insulator and a heat exchanger to do this. Sometimes they run parallel to the ground and other times perpendicular. This one is a perpendicular system, so its set up is much like that of a well running deep in the earth (100' or so). Both systems do have access points in the ground though out.
It is possible that some chemical got into an access point somewhere and sat on the pipe itself.
I can't see how you could be liable for that. Even if you had gotten over spray onto the pipe access point I do not see how it could damage it. Especially if you rinsed everything. How old is the system?
F rank, sounds like he is looking for a scape goat...i would ask for a water sample from the system ..have it run at a lab to see what hard compounds are in it that can lead to corrosion. if levels are high theirs your answer..second there is no way if that pipe is 2 feet plus in the ground our chemical mix would effect it.. also how old is the system...? ..... one finial thing if the pipe is metal and it is direct burial ....the compounds in the soil will corrode it ...these systems should be wrapped to prevent this......do you home work and google geo systems for more teck...data..hope this helps...
Before you go look at it, get the contact info of the installer and give him a call. Explain how we clean, how runoff is diluted and how the SH is biodegradable. He may tell you the homeowner is a pain in the ass. Ask the installer if he has ever run into this before, as we have not. Ask installer what homeowner wants to repair. If it is a small amount, work something out with the installer to kick in a free roof or siding cleaning for him and you may get yourself a referral partner because if he is installing those expensive systems, he is meeting your type of customers. If it is anything substantial get your insurance company involved.
I also think someone is fishing for a scapegoat. The first house I SoftWashed has a geothermal system. It is the home of the previous owner of Water Dragon, and a close friend. I have cleaned his large paver patio once with 4%, and his siding twice with 1%. The paver patio is directly adjacent to the geothermal system area. He has had no problems. Let me know if you need help on this, like the advice of a "third party expert."

I cant see how you could be remotely responsible. Agree scapegoat is what the geo company is looking for. My guess is fly by night or novice goe company did install and cut corners, tons of new start ups out there right now.. Take Chad up on his offer if need be.
