How to determine the right pipe size
Filtercon units are available in a variety of sizes. We work with you to determine the best size for your building, usage and existing infrastructure. To determine the size of your existing water pipe, get a piece of string about 6″ long and find the location of your water supply pipe (either in your garage, side of house or front of house). You will know it’s your main supply pipe when you see a shut off valve that shuts off all the water to your home. Strip away a small section of insulation so that you can get at the pipe and wrap the string around it marking the spot at which it meets itself. Then simply unwrap the string and measure how many inches of string was needed to go around the pipe once. This is the circumference of your pipe. Use the table below to find the corresponding size.
|For Copper Pipe||For Steel or PVC Pipe|
|2.75” = ¾” pipe||3.25” = ¾” pipe|
|3.53” = 1” pipe||4.00” = 1” pipe|
|4.32” = 1 ¼” pipe||5.00” = 1 ¼” pipe|
|5.10” = 1 ½” pipe||6.00” = 1 ½” pipe|
