Hydro-Rain HRZ100 stands in the market with no equal as the industry’s first “one piece” low flow irrigation zone valve, filter, and regulator combination - so compact that it fits in a 6" round valve box!!
On the outside HRZ100 moves away from the competitions traditional plastic construction to a statement of strength and durability featuring commercial ready glass-filled nylon. Inside, HRZ100 can handle water flow as low as 0.38 L.P.M. and pressure to 120 PSI. This model includes a 30 P.S.I. pressure regulator and 200 mesh filter.
- One-piece construction combines low flow irrigation valve, 200 mesh filter and pressure regulator - effectively reducing installation time and parts inventory.
- Accessibility: "Jar-Top" valve and filter are easily maintained, no tools required for service; no valve bonnet screws or bolts to drop into the mud.
- Internal manual bleed. Operate HRZ100 manually with no external bleed stream or use external bleed option for effective “blow out” during seasonal system shut down.
- Compact. HRZ100 is easily covered in a 6" round valve box and up to four will sit nicely in a standard size box.
- 1" Low-flow valve. HRZ100 operates efficiently from 0.38 to 18.93 L.P.M. perfect for residential or light commercial drip or micro watering.
- Water management. HRZ100 features pressure regulation at 30P.S.I. applicable in a range of low flow applications.
- Filtration: Removable “top loaded” 200 mesh filter with easy-flush service cap makes flushing fast and simple.
- Stainless Steel metering design ensures optimal diaphragm performance.
- Durable glass-filled nylon construction for years of reliable operation.

Are there any safety standards my irrigation system must meet?
The main safety concern is regarding the water supply. To avoid contamination of the mains water upstream, in most municipalities, a Dual Check Valve is required at the water connection.
Can I have drip tube & sprinklers on the same irrigation zone?
We definitely don’t recommend it. Typically, drip tube will deliver the water at a far slower rate that sprays. Because of this, if you were to have both on the same zone, the areas with drip would be left far drier than the areas with sprinkler coverage. If you do want to water some areas with drip & some with sprinklers, it can be done, but each will just need to be run on their own separate irrigation zones.
Can I just punch extra holes into my drip tube?
No, drip tube isn’t simply holes punched into poly pipe. Inside each hole is an intricate dripper which delivers that water nice and evenly. Punching a hole will simply create an uncontrolled leak!
Can I just use electrical tape on my cable joins?
Being exposed to the weather, water damage will occur any where water can get in. Electrical tape isn’t quite water tight & over time water will creep into the circuit & create havoc & void all warranties. For this reason you should always use waterproof cable joins like heat shrinks.
Can I run an irrigation system off a regular garden tap?
A garden tap is an excellent place to connect your irrigation system. Ideally, install a connection point behind the tap (turn the water off first) so you can still use your tap to fill a bucket when you need to.
Can I use my solenoid valves off a gravity feed?
Unless your tank located is upwards of 20m above your valves, gravity feed will not provide enough pressure for your valves to reliably open & close. It is not recommended.
Do I need a filter on my irrigation system?
Even on a typical domestic system running on mains water a filter is still a good idea. In the event of a water main fault where rubbish does find it’s way down the line, a filter will protect the system from blockage and or failure. On systems operating off recycled water, like from a tank, a screen filter is mandatory. Debris like silt & dirt from recycled water is the most common cause of blockages of failures in irrigation systems.
Do I need a plumber to install or fix my system?
No, unless you’re tapping into your water supply, a plumber isn’t required. Most domestic irrigation systems can be installed by anyone half handy.
How many solenoid valves should I use?
The number of solenoid valves you use depends on the size of your garden & the flow output of your water supply. The number of litres per minute that are available will determine the number of sprinklers or drippers you can operate at any one time. Once your garden is divided up into each section using that information, you’ll need one solenoid valve to operate each one individually.
How many sprinklers can I have on a single irrigation zone?
Each sprinkler & nozzle sprays water at different rates, but the key factor is the flow rate of your water supply. Work that out with a simple timed bucket test. From there, you can work out how much water each sprinkler you’re looking at uses & work within your flow limit. For more information, check our Product Guides.
I want to design & install an irrigation system. Where do I start?
Well you’re in the right place! We’ve got it all here. The first step, is drawing out a plan of your garden, to scale of course. We’ve got Grid Paper in our Product Guides & all the advice you’ll need in there too!
My solenoid is staying on, how can I fix it?
Nearly all of the time, a solenoid valve staying open is caused by debris caught in the diaphragm. Even the finest debris can cause the valve not to seal shut, causing a constant leak. Other cause can be: Not enough flow because the irrigation zone is too small or, not enough pressure, the valve needs the pressure to seal shut.
Should I flush my watering system before running it?
As you install a system, it’s almost inevitable that small fragments of dirt will get into the pipe, for this reason you should always flush out the system before running it the first time. This can be done by leaving an open end at the farthest point of each irrigation zone & operating the zone for 15 or so seconds to flush it out. Then plug it up & you’re good to go! This can also be said for any other times dirt may have gotten into the system (eg: further irrigation repairs or a mains water supply fault).
What is a master valve, and do I need one?
A master valve is installed upstream of the solenoid valves being used to control each irrigation zone. They’re not mandatory, but they are a good idea as installing one increases the life-span of each valve by protect the valves downstream from the constant pressure that would otherwise be applied. The way it works is, every time a zone is programmed to come on the master valve also switches on, providing the flow, but when all the zones are off, the master valve closes, holding back the flow & pressure of the water supply. Simply, it’s kind of like an irrigation insurance policy.
What is a solenoid valve?
A solenoid valve is the automatic tap that controls that flow of water to an irrigation zone. Solenoid Valves are automatically operated by an irrigation controller which is programmed to tell the solenoid valve when to open & close.
What’s the best type of sprinkler for my garden?
There’s no best type of sprinkler, just better sprinklers for different applications. Gear Drives are better for large areas, over 5m. Pop-Ups are ideal for 1.5-5m & Micro sprays are excellent for anything under that.
Why do my irrigation parts keep blowing apart?
The main cause of blowout is pressure. Whether it’s poly fittings, PVC fittings or timers, whatever the component, if the pressure is too high for what it’s designed for, kaboom! Simply solve the problem with a pressure reducer & make it a brass one if it’s on your water supply.
Why should I buy from an Australian website?
We get any number of calls from people across the country who've bought from overseas & have problems. From electrical output problems to thread compatibility problems & other problems that we aren't able to help with!
By buying from SunshowerOnline, right here in Australia, you can be sure that your warranty issues are covered, that compatibility & compliance isn't an issue & that you'll be able to get helpful after service advice.
Why would I use drip tube instead of sprays?
Drip tube is excellent in areas of rich dense soil where water spreads nicely throughout. Installed under mulch, the water is delivered with minimal evaporation & wastage, going direct to the root ball.
