为公共卫生间更换节水龙头与起泡器（滨海新区文化中心公共广场） / Fit low-flow tap aerators.

滨海新区文化中心公共广场的公共卫生间龙头出水量远高于需要，北方每一升自来水都来之不易，而换起泡器是最便宜的一步。 / The public washroom taps at the Binhai Culture Centre public plaza run far harder than they need to, every litre of mains water in the north is dearly bought, and an aerator swap is the cheapest first step.

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

更换前后逐个流量实测＋器具型号记录＋前后照片 / measured before/after flow per fixture + fitting model record + before/after photos

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. 逐个龙头实测更换前流量。 / Measure the flow of every tap before the swap.
2. 关闭角阀，拆下旧起泡器并清理螺纹。 / Close the isolating valve, remove the old aerator and clean the thread.
3. 装上节水起泡器并拧紧至不渗漏。 / Fit the low-flow aerator and tighten until it does not weep.
4. 逐个实测更换后流量。 / Measure the flow of every tap after the swap.
5. 汇总每台节水量并拍摄前后照片。 / Total the litres saved per fixture and photograph before and after.

What counts as done

• 更换前逐个龙头流量记录 / Measured flow of every tap before the swap
• 更换后逐个龙头流量记录 / Measured flow of every tap after the swap
• 所装节水件型号与数量 / Model and count of the low-flow fittings installed
• 前后照片与无渗漏确认 / Before and after photos with a no-weep confirmation

Proof is measured against these, not judged by taste.

The standard this serves

Water Efficiency. Water efficiency is the quiet discipline of wasting nothing indoors. The EPA's WaterSense program sets the marks: how many gallons a minute a faucet should pass, how to find the leak that runs a toilet all night, how a household's water bill tells a story. Mastery looks like an auditor who can walk a home in an hour and find every hidden gallon. The skill is built one fixture at a time, which is exactly what this packet asks: measure one flow, find one leak, record one truth about where the water goes.
