Why so “cheap” at CheapSprinklers? Low prices by design — same parts, no compromise

Our prices are lower because of how we run our business — not because the product is different — and we pass those efficiencies directly on to you.

You’re receiving the same brand-new, factory-sealed item sold by big-box, supply-house, or bloated online-warehouse sellers — delivered direct to you, for less.

  • Bulk Purchasing: We buy in high volume to lower per-unit cost
  • Low Overhead: No physical storefronts or unnecessary middlemen
  • Price-First Model: Our business is built around keeping everyday prices as low as possible — so you can put the savings toward other projects or your business.
  • Fast & Efficient Fulfillment: Streamlined US warehouse operations keep costs down and orders moving fast.

The Result: Genuine products with full manufacturer warranty — delivered fast, without paying inflated big-box, supply-house, or bloated online-warehouse markups for the same parts.
