Swap the water-filter cartridge on schedule.

A nitrate filter only protects a family while its cartridge is fresh. In the Lower Yakima Valley, homes that got filters often miss the change date because cartridges cost money and the date slips by. A quarterly swap round keeps installed filters actually working.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash: recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

before/after cartridge photos plus the updated date card

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Steps

1. Confirm the host's invitation and check the date card on the installed filter.
2. Shut the supply valve and swap in the correct replacement cartridge per the manufacturer's instructions.
3. Flush the new cartridge for the required time and confirm clean flow.
4. Update the date card with today's date and the next change date.
5. Photograph the old cartridge, the new cartridge in place, and the updated date card, GPS-tagged and dated.

What counts as done

• Photo of the spent cartridge removed
• Photo of the new cartridge installed
• Photo of the updated date card
• GPS coordinates and date

Proof is measured against these, not judged by taste.

The standard this serves

Drinking Water Safety. Drinking water safety rests on hard numbers: the EPA and the World Health Organization publish exact limits for lead, bacteria, nitrates, and the rest, the line between water that is safe and water that only looks safe. Clear water can fail the test; slightly cloudy water can pass it. Only the test knows. Mastery means clean sampling habits, honest custody of every sample, and readings a stranger can trust. This packet is one correct sample or one careful reading, taken by the book. Every safe glass of water stands on somebody having done this properly.
