Designed for large volume flow.Reducing to 3/4" creates WAY TOO much back pressure for this pump. (Back pressure creates HIGH Total Dynamic Head - TDH)In your scenario, Let's say your irrigation system requires a flow rate of 15 GPM @ 35 psi @ 300 ft away from pump Running 15 GPM thru 3/4" pipe for 300 ft = ~130 ft TDH (Pressure Loss = 56 psi)Plus the 25 ft rise (Pressure loss = 11 psi)And let say you want 35 psi (Higher PSI = Higher TDH) = ~80 ft TDH (Pressure Loss 35 psi)That said, you would need a pump that can operate upwards of 235 TDH (Pressure loss to overcome = 102 psi)The GT15 has a MAX TDH of ~120 ft TDH (or ~ 52 psi) Don't use this pump for your system...it will not work. **Q: is it possible to over-work this pump by not having enough sprinklers in a zone?** A: No the problem on pumps is typically when you over flow them (too many sprinklers) and the motor draws more amps. Also cycling the motor on/off is not good for the motor life. **Q: I’m replacing a sta-rite ds3hf-01 1.5hp, would this be the correct replacement pump?** A: Yes these have similar pump curves. ## Frequently Bought Together - GOULDS PUMPS GT15 IRRI-Gator Self-Priming Single Phase Centrifugal Pump, 1.5 hp, Blue - Blue Devil Adjustable Motor Cover, water resistant - Super Pro 80960BU Pool Spa Filter Water Pressure Gauge, 0-60 PSI, Bottom Mount, 1/4-Inch Pipe Thread --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/271101577-gt15-irri-gator-self-priming-single-phase-centrifugal-pump-1](https://www.desertcart.co.za/products/271101577-gt15-irri-gator-self-priming-single-phase-centrifugal-pump-1) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-05*
