Absolute Plumbing in Kansas City sucks

Do NOT use this company for any plumbing needs.  They installed a new water heater at my house and two years later this is what it looks like.

The owner of this company insists that it’s a leak above the water heater and that it was NOT an improper installation.  I’ve checked the area and there is no moisture.  He won’t even send someone out just to check on it.  He claims that the work is only warranteed for 30 days, which is mostly useless because corrosion of this sort would not appear within that amount of time.  DO NOT USE ABSOLUTE PLUMBING.
