Frequently Asked Questions (FAQs)

Why won’t my shallow well pump build pressure?

If the shallow well pump is not building pressure, check if there is any internal damage to the impeller, seal, or bearing. This damage can cause the inability to build pressure. There might also be clogging issues. See if there is any debris in the pump compartments.
