## Questions & Answers

**Q: Is this suitable for use with an artesian well? (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

### ⭐⭐⭐⭐⭐ Heavy duty
*by L***A on February 14, 2025*

Good old school well cap

### ⭐⭐⭐⭐⭐ Heavy duty
*by M***S on August 27, 2024*

This is a quality item. The only thing that needs changing is the bolts should be stainless steel. My old seal had galvanized bolts which were so rusted they couldn’t be removed when the well pump died. I’ve tried contacting Merrill but the website option doesn’t work and they don’t list a phone number. I found SS metric bolts online and replaced the galvanized ones.

### ⭐⭐⭐⭐ Good but with one drawback (which I think I solved)
*by T***Y on April 1, 2025*

The product looks and expands great to seal. The only BIG drawback is if I forget, or a well service company doesn't know, if you remove both bolts from either side, the bottom halves can fall down into the well.I just got an idea how to solve that problem! If I (or you) thread a nut on the bottom of the bolts and use RED Locktite on the threads, the bolts can be loosened all the way without fear of turning the bolt all the way out. I didn't return it yet, so I may try this without the locktite for a test fit. If needed, I can buy longer bolts.
