Sump pumps & basement waterproofing

Sump & Seal

Sump & Seal is MadGrey LLC's basement water site, written for the homeowner who has water on the floor right now or a pump that has just quit. Its own line is the whole editorial premise in a sentence: sump pumps, backups, parts and waterproofing explained by what actually fails.

What the site covers

The site exists because of a gap it names plainly. Search any sump pump symptom and the results describe the problem accurately, identify the cause correctly, and then stop at a contact form — the missing piece is always the name of the component that failed. A failed check valve is the most common reason a pump looks like it is dying, a stuck float switch is the most common reason it will not start, and neither is a pump failure: both are parts you can hold in one hand and both cost a fraction of a service call. Eight sections carry that premise across what the site states as 90 guides, roundups, comparisons and reviews covering 56 products: primary sump pumps by horsepower, pit size, housing material and switch type; backup systems, meaning battery backups, water-powered backups, combination units, AGM batteries and generators; parts, which is where the check valves, float switches, basins, pit covers, discharge kits, freeze-relief fittings and backflow preventers live; water alarms and leak detectors, including Wi-Fi sensors, pump monitors and automatic shutoff valves; waterproofing, from masonry coatings and hydraulic cement to crack injection and exterior membranes; crawl spaces; five brands read one at a time; and a guides section organised symptom by symptom — a pump that keeps running, a pump that will not start, a breaker that trips, a discharge line that freezes, a basement that has already flooded.

Two editorial rules govern everything on it, and the first is the one the category gets wrong. A pump's headline gallons-per-hour figure is measured at zero feet of lift, which describes the pump lying on a bench with the outlet open; a real basement asks it to push water eight to twelve feet up and twenty to thirty feet out, where it delivers substantially less. Every flow figure on the site is therefore stored with the lift it was measured at, enforced by the content model, so a reader is never handed a bench number as though it were real-world performance. The second rule is that where a figure cannot be sourced it is omitted rather than estimated: every specification traces to the manufacturer's documentation or a retail listing, cited at the foot of the page, and where sources disagree the page says so. Picks are scored on a ten-point scale across five published criteria — flow at lift, build, switch, serviceability and value — with the switch weighted heavily because the switch is the part that fails before the motor, and every product entry carries a "skip this if" line naming who should not buy it, on the site's own stated ground that a recommendation nobody should avoid is an advertisement rather than a recommendation. It is equally direct about its limits: there is no test bench, no lab and no fleet of pumps in a warehouse, it does not own most of the products it writes about, no price appears anywhere because prices in this category move weekly, there are no customer quotes or testimonials, its scores are editorial judgements that are deliberately kept out of its structured data, and there is no licensed plumber, engineering degree or certification behind the bylines. Where a problem is structural, electrical or genuinely a job for a professional, the page says so and sends the reader to one.

That is the same arrangement MadGrey LLC runs on every site it operates. Sump & Seal is free to read and funded by affiliate commission as a participant in the Amazon Services LLC Associates Program — if a reader buys through a link the retailer may pay a commission, at no extra cost to them — with every outbound buy link marked rel="sponsored nofollow" and carrying a visible #ad marker beside it. Commission rates are not a ranking input: nobody pays to appear, no manufacturer has any involvement in the content, and pages routinely conclude that the cheaper product, or a free fix such as clearing the gutters, extending a downspout or re-routing the discharge, is the right answer. The photographs are licensed stock, credited on the site, and are never presented as its own premises or equipment. The disclosure sits on the site itself rather than buried in a footer, and the basis for a recommendation is always stated, because a reader can only weigh a pick if they know what it rests on.

Coverage

  • Sump pumps — primary pumps ranked on flow at real lift, split by horsepower, pit size, housing material and switch type, with submersible against pedestal, cast iron against plastic, and 1/3 against 1/2 against 3/4 HP compared head to head
  • Backup systems — battery backups, water-powered backups, combination units, AGM deep-cycle batteries and generators, with the runtime question answered in gallons pumped rather than hours elapsed
  • Parts — check valves, float switches, basins, pit covers, discharge kits, freeze protection, radon-sealed covers and backflow preventers, which is where most pump problems actually get fixed
  • Water alarms and leak detectors — standalone alarms, Wi-Fi sensors, sump pump monitors that warn before water arrives, automatic shutoff valves, and where in the house to place a sensor
  • Waterproofing — masonry coatings and what they cannot do, hydraulic cement for an active leak, epoxy against polyurethane crack injection, exterior dimpled membranes, window well covers and dehumidifiers with condensate pumps
  • Crawl spaces — vapour barriers and thickness, encapsulation kits and what they leave out, low-clearance pumps and pits, and crawl-space dehumidifiers
  • Brands — Zoeller, Wayne, Liberty Pumps, Superior Pump and Basement Watchdog read one at a time on published data, plus the head-to-head comparisons readers actually search for
  • Guides and troubleshooting — sizing by measured lift, pit sizing, pipe sizing and routing, installation, the quarterly test, the maintenance schedule, lifespan, and a symptom-by-symptom set covering a pump that keeps running, one that will not start, a clog, noise, a tripping breaker, a frozen discharge line and a basement that has already flooded

A reader gets the failed component named rather than a quote request, flow figures published with the lift they were measured at instead of the bench number, five scoring criteria with the switch weighted heaviest because that is what fails first, a "skip this if" line on every product, a source printed at the foot of every page, and no price on the page that would be wrong by the time they read it.

How this site is funded

Sump & Seal earns affiliate commissions on some links to retailers. Those commissions never influence which products are recommended or how they are ranked. The full affiliate disclosure sets out how it works across every site MadGrey LLC operates.
