This page explains how we evaluate and recommend well system equipment, pressure tanks, well pumps, pump controls, and related parts, so you know what our recommendations are based on before you rely on them.
What our evaluations are based on
We do not physically install or run every pump and tank we cover. Our evaluations are based on manufacturer specifications, technical documentation, industry sizing standards (such as Amtrol’s ESP I/ESP II method), and cross-referencing published data across brands and model lines. Where a claim can’t be traced back to a manufacturer source, we say so or leave it out rather than estimate.
What we evaluate
- Specifications versus the label. For pressure tanks, we look at actual drawdown at common switch settings (30/50, 40/60, 50/70), not just the labeled tank volume, since usable water is typically only 25 to 35 percent of the labeled size.
- Sizing fit. Whether a product is adequate for its stated use case, for example, whether a tank meets ESP I or ESP II minimum run time for a given pump horsepower, or whether a pump’s GPM and head match common household demand.
- Build and materials. Port size and thread type, tank material and liner type, motor housing and cable specifications, listed where the manufacturer publishes them.
- Warranty. Length and terms of the manufacturer’s warranty compared to others in the same category.
- Price relative to specification. Where pricing data is available, how a product’s cost compares to others with similar drawdown, flow rate, or protection level.
- Manufacturer track record. Whether the brand has a consistent catalog history and parts availability, which matters for replacement and cross-reference searches.
What we don’t do
- We don’t claim to have physically tested a product unless that’s explicitly stated in the article.
- We don’t accept payment from manufacturers or retailers for favorable placement or reviews.
- We don’t recommend a product outside its rated use case just because it’s part of an affiliate program.
Pros, cons, and who shouldn’t buy
Every product recommendation includes drawbacks alongside strengths, and we call out when a product is a poor fit, for example, undersized for a high-demand household, missing a common port size, or discontinued with limited parts support.
Keeping this up to date
Manufacturers revise model lineups and specs over time. When we become aware of a change, we update the relevant article and its “updated” date. See our Editorial Policy for our sourcing and correction standards, and our Affiliate Disclaimer for how affiliate links work on this site.
