DIY: Sump Pump Installation Guide

Keep your basement dry — install your own sump pump this weekend, and skip the $1,200–$3,000 contractor bill.

A sump pump is the cheapest flood insurance you'll ever own, and installing one is an honest weekend project: break a small square of concrete, dig the pit, set the basin in gravel, and plumb one pipe up and out of the house. This guide walks you through every step in plain English, with real photos, real costs, and the contractor's judgment calls written down — including the two parts everyone gets wrong (the check valve and the weep hole) and the discharge mistakes that make a pump pump its own water in a circle.

Written by Rafael Reynoso, a licensed contractor who has spent his career inside hundreds of homes, in the friendly, no-jargon HomeReady Guides style.
