Water Source Connections
Hooking the system to the water supply. You have two choices for connecting your system to your household water supply.
- Plumbing the system directly into your water supply. This is the most common method to hook up sprinkler systems but does require knowledge regarding municipal regulation and does require some plumbing expertise. The diagram below may give you some guidance if you want to tackle this on your own.
- Using Your Hose Bib (Faucet). This is the simplest way to hook your system but is only recommend if your zone flow rate (which we calculated in the first steps) is lower than 180 gph for each zone. You can stretch it out a beyond that flow, but we just like to plan on the safe side of water flow when using this method due to the flow limitation for most hose end timers. You have two choices when using your hose bib as your connection point.
- Using Solenoid Assembly (Preferred). Employing this method is beneficial and necessary if you have more than 4 zones, and you want to use accessories such as rain sensors and have the capability of WIFI and or Bluetooth Control via your Irrigation Controller.

When connecting directly from the Hose Bib to the Solenoid Assembly, you must consider a few things.
Firstly, the tubing that will be running from the Bib to the Assembly will be under constant pressure, so you must use a ¾” Poly Tubing with a 100 PSI rating.
Secondly, since the Hose Bib is Hose Thread you must convert from Hose Thread to Pipe Thread fittings which will accommodate the 100 PSI tubing.

C - ¾” Female Pipe Thread x Insert
- Using a Hose End Timer – When using a Hose End Timer, it will take the place of all solenoids in your system. We recommend using this method for smaller residential systems with flow rates of 180 gph or less, but as we mentioned previously you can stretch the limits and you’ll likely be fine. One thing to note when using a Hose End Timer is the ability to light commercial use fittings and tubing which will make installation easier. Since there is no section of the system under constant pressure you are able to use a tubing such as our DD-DH940 Tubing which is available in 100 and 500 ft rolls.

Hose End Timers are available in Single Zone, 2 Zone, and 4 Zone models. Shown here is a 2 zone timer, and as you can see the zone tubing is attached directly to the timer using a Swivel Hose Perma-Lock fitting. One drawback using this system will be having all of your zone tubing visible above ground.

Your system is pretty much planned at this point, and you’ll just need to choose a few additional components and be sure to not forget a few things that will make your life easier on your installation.
Controller: If you are going to use a solenoid assembly for your system, you will need an Irrigation Controller. You have plenty of options when it comes to a controller for your system. Our recommendation is the purchase an indoor/outdoor controller to give you options regarding where to place the controller, and also purchase a controller with 1 or 2 additional zones to provide you with the option to expand at a later date. For ultimate performance and convenience, we recommend the Hydro-Rain HRC-400 controllers which have features such as WIFE and Bluetooth and are known for their simplified interface for easy programming.
Irrigation Wire: You will also need wire to go from your controller to the solenoid assembly. Each solenoid will require one conductor and there is a neutral wire for as well which are spliced together. You will need to order wire with one additional conductor than the solenoids you are using.
For example, if you have 4 solenoids in your system, you need to order 5 conductor wire (18 5 100 Wiring). Also, don’t forget to order watertight silicone nuts (WPWN-S), you will need one for each valve and an additional one (medium size WPWN-M) to splice together the common wire, so in this case you would need 4 small and 1 medium sized nut.
Valve Box: If you plan on burying your solenoid assembly, you will need a valve box to protect them. If you have 3 or less solenoids, the NDS 115 TBC will cover, and if you have 4-5 solenoids the NDS 119 TBC would be needed. Also, you may need a smaller round box to cover drip zone assembly if needed.
Tools: A good Cutting Tool (BLP-CUT-25-1X), Teflon Tape (TEFL-STD), and a few commonly found tools in most toolboxes.
