Ball Valve 2”spg x 2”spg

The 2" SPG x 2" SPG Ball Valve is a heavy-duty PVC ball valve with 2-inch socket-and-glue (SPG) ports on each side. It's the standard shut-off valve used in spa plumbing where you want the ability to isolate a section of plumbing for service — typically immediately upstream and downstream of a pump or heater so the component can be removed without draining the entire spa.

When you'll need to install or replace one: Replace the ball valve when the handle has gone stiff, the seal has started weeping, or the valve body has cracked from freeze damage. New installations are typically part of an equipment-bay rebuild or a service-friendly retrofit (older spas often skipped the isolation valves to save cost; adding them later makes future service much faster and cheaper).

How to install: Cut the existing 2" PVC plumbing cleanly, deburr the cut, prime both the pipe and the valve socket with PVC Primer, apply Weld-On 747 PVC Cement to both surfaces, push the valve home with a quarter-turn, hold for 30 seconds, and let cure 30 minutes before pressure. Keep the valve in the OPEN position during cure so you can confirm flow once you restart.

Quick tips:

• Always use blue spa-rated cement (Weld-On 747), not grey general-PVC cement
• Drain the spa before cutting plumbing — obvious in retrospect, easy to forget when you're focused on the valve install
