Carolyn C San Tan Valley , AZ August 29, 2016 I needed an o ring for my whole house water filter Ordered an o-ring (plus a spare!), removed the old misshapen one, and, Harrah, no water leaks. I was completely amazed that it got here within just a couple days! Thank you! 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
