1 Water Source Connection
Our sample Drip Irrigation system is using a 1" Distribution Line from the water source. We likely could have used a 3/4" line but its often advisable to oversize your main distribution lines to avoid excessive pressure loss and to leave excess capacity for the possibility of future expansion. Even if your water source is coming from a 3/4" hose bib you step up the connection to accommodate the larger tubing size. Below is a typical parts configuration from a 3/4" hose bib to a 1" Polyethylene distribution line.
![]() | 439-131 | For this example we are connecting to a 3/4" male hose bib. This fitting then increases the thread size to 1". If your thread size is different a combination of parts can always be found in our Sprinkler Fittings category. |
![]() | 61793P | 1" Check Valve. A check valve is necessary for any drip irrigation system using a residential water source to avoid back flow into the drinking water system. If your system is using a water source specifically for the irrigation system a check valve is likely not necessary. |
![]() | DF100-140 | Filteration is critical for successful operation of any drip irrigation system. Even though we also inclduded filter for every drip zone it is often advisable to have additional filteration at the water source. |
![]() | 1435-010 | Female adaptor for connecting to poly distribution line. Clamps are required when using insert fittings. |

![]() | 37678 | If using Blu-Lock For your distribution lines you will also need a 1" threaded coupling (430-010). |
We will now move on to the components for drip zones and drip line connections.
