CVNL300 — Merrill 3" No-Lead Brass Check Valve (700 Series).
A check valve keeps water moving one direction only, so the column of water in a well's drop pipe can't fall back down the well between pump cycles and force the pump to re-prime and re-pressurize every time it starts. Merrill's 700 Series check valve uses a no-spin poppet design that seats the same way on every cycle instead of rotating and wearing unevenly, which keeps it sealing reliably over years of continuous cycling.
Specifications:
- Pipe Size: 3"
- Material: No-Lead Brass
- No-spin poppet seats consistently every cycle for a reliable, long-lasting seal
- Prevents backflow that would otherwise force the pump to re-prime on every cycle
