Frequently asked questions
What pipe is normally used for pool plumbing?
Rigid pressure-rated PVC is common for permanent residential pool circulation.
Does larger pipe always improve flow?
Larger diameter can reduce friction, but the complete system must still be engineered correctly.
What is a pool diverter valve?
It directs or proportions flow among suction or return lines.
Why are check valves installed?
They prevent reverse flow in selected heater, solar, spa or chemical-feed arrangements.
What is the purpose of a union?
It allows equipment to be disconnected for service without cutting the pipe.
Can flexible hose replace rigid PVC everywhere?
No. Use only products approved for the exact pressure, environment and installation.
How can plumbing restrictions be diagnosed?
Compare pressure, vacuum, flow, valve position and equipment condition under controlled tests.
Who should alter buried pool plumbing?
Use a qualified pool plumber for pressure testing, rerouting and permanent repairs.
