Guttering and Drainage Calculations - $25

Complete calculations with backup data on the recommended sizing of your site. Send zip code and square footage of roof and get back proper design alternatives for both the IPC and UPC plumbing codes. The reports include a 100-year rainfall map for your area.

Typically you will need at least 2 reports and sometimes 3 (i.e. 1 gutter calculation, 1 downspout calculation, 1 drain pipe to cistern or stormdrain calculation). Each report is $25, usually two reports, but will confirm number prior to proceeding.

These calculations are required to properly size your conveyance/drainage system. Undersizing your system can result in system failure and oversizing results in spending more money than you should be.

Floating Extractor - $15.00

Save money, build your own from parts available at most hardware stores.

Why worry about where the water in the tank is pulled from? Isn't it all the same? The simple answer is NO. No matter how good your first flush system, if you have one at all, some particulates are going to enter the tank. Eventually, this material will settle on the bottom of the tank. So taking water off the bottom picks up these particulates. Some may be caught by an outgoing filter but this water may also contain heavy metals or chemicals which, at worst, may not always be filtered out and at best, will clog the intake filter faster.
