Last updated 2026-10-15. Hard Water Feed, a DBA of Compton Consulting Incorporated (Ohio). Every number here is read from the same place the terms read it, so the two cannot disagree.
Every newly filed domestic water well in your territory, ranked by the measured hardness of the groundwater near it, with a printable water report for each address; a 6×9 postcard mailed in your name to every one of them that has an address a card can be posted to; and the list of exactly who was mailed. What arrives shows a real week.
$2.50 per card mailed, billed weekly for the cards mailed that week. The list and the reports come with the cards. A week with no new wells costs nothing. The price is the same in every territory and is not negotiated.
Yes. Your first 4 weeks are free, up to 60 cards: you see the real cards and the list of exactly who was mailed before the first invoice. The price per card is the same afterwards; it is a trial, not a lower rate.
Whatever you set. You can give your territory a weekly bill ceiling; cards over it roll to the following week rather than being dropped. You can also set a daily limit on how many go out.
Your state’s page shows the card its homeowners receive — for example Ohio’s. The front carries the area’s hardness, what hard water does to a house, and your free in-home test; the back carries your name, telephone number and licence number where your state requires one. Every card says ADVERTISEMENT, names you as the sender, and says why it arrived: a new well filed in public state records at that address.
Yes. Nothing is mailed until you have approved a proof with your name, telephone number and offer on it. A later change to the card means a new proof first.
Once we have watched it deliver for 8 measured weeks, so that we can tell you what a typical week looks like before you pay for one. The territory map shows how many of the 8 weeks each territory has measured and the earliest week it could open.
By a card on file, billed weekly in arrears for the cards that went to print, one invoice listing every card. Our payment processor is Stripe; we never see or store your card details.
Stop any week by email. No cards go out after the week you tell us, and you pay only for cards already mailed. There is no minimum term and no notice period.
Yes. Ask us to mail nothing for a while and the territory is held for up to 60 days; a pause does not lapse your exclusivity. After 60 days it returns to open.
Only by not mailing it. Exclusivity is held by mailing every new well; if a weekly ceiling or daily limit you set leaves new wells unmailed for more than 4 weeks while the territory is active, the hold lapses and the territory may be offered to another dealer. Raise the ceiling, or pause instead, and it does not.
Yes. A card the Postal Service returns to us was printed and mailed. Your weekly list marks it as returned, so you can see which addresses the mail is not reaching.
Hard Water Feed, a trading name of Compton Consulting Incorporated, an Ohio company. The postal address is at the foot of every page and on the terms.
The well records we read are published by each state under its public-records law, and we have checked each state’s statute before reading it (the privacy page lists them). Mail has no Do-Not-Call register; we hold no telephone numbers, so nothing here can produce a cold call. Every card carries the sender, the word ADVERTISEMENT, and the reason it arrived. Our terms have not yet been reviewed by a lawyer, and the terms page says so.
Ask them before the proof, not after. Only what you approve goes on the card, and a card can carry your trading name without a logo if that is what your brand agreement allows.
The card is addressed to Current Resident, names you as the sender, and says it came from a public well filing. A homeowner who writes to us is taken off every future list before the next batch, and we tell you. We cannot remove anyone from the state’s own record; nobody can.
Every week you receive the list of exactly who was mailed, address by address, beside the invoice for that week. Every card is logged when it goes to print.
It is an area figure, not a test of that house: the median of laboratory samples from tested wells in the same grid square, or the county median where too few nearby wells have been tested, and the card says so. Where there is no figure at all, no card is sent. The method is published.
You are billed for cards mailed, so a quiet week costs little and an empty week costs nothing. We do not promise a fixed number of wells; filing volume is bursty, which is why a territory rather than a county is sold.
The week is the filing week. Wells are often filed weeks after they are drilled, and nobody working from the public record can do better. The card goes to print the week the filing reaches us; our one measured house test took 13 days from order to the last card in hand.
Not from us. One dealer per territory, for as long as it is active. The records themselves are public and anyone may download them; what you are buying is the qualification, the reports, the mail and our promise not to sell them to your competitor. Neighbouring territories overlap at the edges.
Work the addresses, knock on them, put your branding on the reports, load it into your CRM, and keep everything you have received if you cancel. You may not resell or share it with another water treatment business.
Not without 30 days’ notice, and never on cards already mailed.
A territory is offered only when it produces at least 100 printable cards a year and at least 50% of its new wells have an address a card can reach. Below that a dealer would be paying for silence. Tell us where you work and we will say whether it clears the floor.
Not yet, and this page will say so until it is false. There are no testimonials because there are no customers.
We do not know yet, and will not quote a number we have not measured. What we can give you is the arithmetic: at a typical $1,000 gross profit on an installed system, one install in every 400 cards pays for all 400. Hold your own close rate against that.
The terms on this site are the agreement, and they are what you are agreeing to when you put a card on file. If you want a signed page, we will put your territory’s name on one that points at them.
