Frequently Asked Questions

How do I know what size Surge Valve I need?

The easiest way to identify the size is to remove the bite valve from the tube. The bite valve is connected to the tube by friction, so pulling it out with a little force will not do any damage to your system. Once the valve is removed, count the number of barbs on the valve. If you have 2 barbs, the size is a 1/4". If you have 3 barbs, you have a pre-2011 5/16".
