E-E-A-T Hiring Advice

4 Essential Questions to Ask Before Hiring a Rainwater Installer

Rainwater harvesting involves structural engineering, filtration, and plumbing compliance. Before signing an installation contract, ensure your contractor addresses these key items:

  • Professional Credentials: Are they ARCSA Accredited Professionals (AP) or licensed plumbers certified in backflow prevention?
  • Pre-Filtration Sizing: What micron rating and first-flush diversion volume are they designing to prevent gutter sludge from reaching storage?
  • Tank Specifications: Are storage containers opaque, UV-stabilized, and certified to NSF/ANSI 61 if utilized for indoor or potable use?
  • Permits & Rebates: Will the contractor pull required municipal plumbing permits and submit utility rebate paperwork on your behalf?
