(i.e. will it stop well at about 10 psi from overflowing)** A: This could stop flowing water but only if the 1/2" vent tapping is plugged and the gaskets supplied are used plus some sealant around the electrical wires that pass thru the well seal. Close attention to detail is required, **Q: Is the 1inch center hole for 1" poly pipe which has a 1.125inch outer diameter? whats the 1/2inch hole for? is the 1inch fip for a cable gland?** A: Yes thev1” center hole is for the pipe to the pump. The 1/2” tapped hole is for a vent so air can move in and out as the water level changes in the well. The 1” tapped hole is for the conduit or electrical cable for the pump. **Q: Will this fit a pvc pipe with an id of 5 7/8"?** A: If you push the bottom two plates together on the well seal then they should just fit inside your 5 7/8" ID PVC pipe. This is border line and we trust your PVC pipe is the round and not egg shaped so the well seal can fit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made *by D***. on June 22, 2025* Worked well for my use.
