New irrigation system

Folks

This is for our frontyard in NYC where we have no water connection today. We want to plant a variety of flowers, some blueberry trees, a little lawn and think of doing an irrigation system in the future (total area 40x30). My contractor wants to buy something like this but it only provides a single hose connection and rated at 125 psi

3/4 in. x 12 in. Brass Anti-Siphon Frost Free Sillcock Valve with Push-Fit Connections-P140-8-34x12 - The Home Depot

If I attach a 4-way converter in the future (only plan to use 3 connections), will it work or will it have too little pressure? I need 2 connections for irrigation systems (left and right side) and 1 hose just for washing the car, etc

Thanks!

You said irrigation system but then linked to a hose bib/spigot. Will you have an automatic irrigation system or are you going to be watering by hand?

The big danger of using a frost free sillcock is freezing weather. You should NEVER leave ANYTHING connected to the faucet when there is the chance of freezing. If you do it's a surprisingly reliable way to burst the sillcock's body up inside the wall where it will leak into the house. This is less an issue when you use a hose for watering as many people put their hose away in winter. When you start putting on a splitter and leave things connected semi-permanently it just begs to be left connected (forgotten) and sure enough a surprise cold snap freezes it.

I would go with a sillcock like you linked and plan on hand watering with a hose. If you are doing a automatic irrigation system I would do it properly with the water lines buried and your controller either underground or inside the house where it's protected against freezing.

I may be using wrong terms but we plan on a drip or a soaker hose system. We'll disconnect whatever components that need to be disconnected before winter. This system is not going to be in place till next summer but for now, we are simply planning for it (we will only use a water hose for the remaining part of the summer)

Thx

You have two ways of going.

A fully automatic system that gets connected directly to the water supply line. The lines are usually run underground and the main line would run into a basement. This system could be several zones and run on a time clock. This type of system needs to be blown out in the winter.

Or... just use basic soaker hoses and turn them on when needed.
