WARNING: Motor Warranty Not Honored after 6 Years
WARNING: ThinkVacuum Refused to Honor Their 25 Year Motor Warranty That They Advertise on their Drainvac product line after a bearing failure at 6 years.
The motor bearings failed in my 9-gallon Viper DrainVac after about 6 years. The shaft developed severe wobble and the motor eventually stopped turning.
When I contacted DrainVac for warranty support, they refused the claim because I could not provide proof that the motor brushes had been replaced every 5 years or 500 hours.
That explanation makes no sense. Motor brushes have nothing to do with bearing failure, yet they used that requirement to deny the warranty claim. It feels like a technical loophole designed to reject claims rather than stand behind the product.
After denying the claim, they wanted to sell me a motor for $349 that I could buy elsewhere for $124, or a complete new unit for $1049, full price as listed on their website.
If you're considering buying one of these units, assume the motor warranty is essentially meaningless unless you have detailed maintenance records for brush replacements.
Disappointing experience.
