Contact RainSave

RainSaveis a small, independent, ad-supported site — there is no support desk standing by, but a real person reads everything that comes in to support@popleak.com.

A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the rain barrel calculator, household water use calculator, leak drip loss calculator, irrigation timing calculator, greywater calculator, or water savings calculator— and the values you entered); a tool you wish existed on the site; an error or unclear step in the blog, learn section, or the museum; or a bug in how a page looks or behaves on your device.

There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. If your question is really “is a rain barrel or greywater system legal on my property?”, your local water utility or building department will serve you far better than this site can: RainSaveprovides general-purpose calculators and explanations, not a site inspection or a permitting decision, and it isn’t affiliated with any water utility or local government.

Before writing in about a tool result, it’s worth double-checking the numbers you entered — a mismatched unit (gallons versus liters, square feet versus square metres) or a mistyped value is the most common source of a surprising answer. If it still looks off after that, that’s exactly the kind of message worth sending.
