Product quality problems

Malfunction The tank is leaking at the main seam after only 9 months. The original OEM unit lasted 15 years. There has been some confusion as to who is handling the 30-day guarantee returns - Revain or Dorman, but Revain has rectified the situation by offering a return or refund.
