About Sump & Seal
A publication about keeping water out of basements, written for the person who has water in one right now.
Why this site exists
Search any sump pump problem and you will find the same shape of page over and over: an accurate description of the symptom, a correct identification of the cause, and then a contact form. The part that is missing is always the same — the name of the component that failed and where to get another one.
That gap is a business model rather than an oversight, and it is the reason Sump & Seal exists. A failed check valve costs a fraction of a service call. A stuck float switch is a twenty-minute job with a screwdriver. Most of what goes wrong in a sump pit is a part you can hold in one hand, and naming that part is the whole editorial premise here.
Who writes it
Sump & Seal is written by Brijon M., the hands-on owner behind MadGrey LLC. The site is owned and operated by MadGrey LLC.
We are going to be direct about credentials, because this category is full of invented ones. There is no licensed plumber on staff, no engineering degree behind the bylines, and no certification to display. What there is: careful reading of manufacturer documentation, consistent sourcing, and a refusal to publish a number we cannot trace. Where a question needs a licensed professional — structural cracks, electrical work, anything involving a gas appliance — the page says so and sends you to one.
What we do not claim
Three claims appear constantly in this category and none of them are true of this site:
- We have not tested these products. There is no test bench, no lab and no fleet of pumps in a warehouse. Any site claiming otherwise about a catalog this size is describing something that did not happen.
- We do not own most of these products. Where a page describes how something behaves, it is describing published specifications and documented behavior, not our experience of a unit on a shelf.
- The photographs are licensed stock. They illustrate; they are not our premises, our work or our equipment. Credits are on the image credits page.
What we do instead is published, checkable work: every specification traces to the manufacturer or a retail listing, every source is printed at the foot of the page, and every flow figure is stored with the lift it was measured at — because a flow rate without a lift is marketing rather than data.
What is on the site
90 guides, roundups, comparisons and reviews across eight sections, covering 56 products. The sections are pumps, backup systems, parts, water alarms, waterproofing, crawl spaces, brands, and a troubleshooting library organized by what you are actually seeing rather than by what the manual calls it.
If you are in a hurry, the fastest routes in are sump pump keeps running, sump pump not working and basement flooded: what to do.
How it is funded
Affiliate commissions, disclosed on every commercial page and explained in full on the affiliate disclosure. Nobody pays to appear here, no manufacturer has any involvement in what we write, and we say plainly when the cheaper option is the better buy — which happens often in this category.
Getting in touch
Corrections are genuinely welcome, particularly on specifications. If a figure here does not match the manufacturer's current documentation, tell us and we will fix it and say that we did. Email contact@sumpandseal.com or use the contact form.
