2 zone water timer buying guide
Updated: October 2026
You have one outside tap and two areas that cannot share full flow at once. A 2 zone water timer buying guide should settle the class before you stare at stars: whether automatic watering is allowed, how often each outlet must start, keypad or Zigbee, and whether the inlet will survive a UK bib tap. The six kept listings sit on the [2 zone water timer comparison](/hub/garden-watering/2-zone-water-timer). Peter F. updated this on 21 October 2026 from amazon.co.uk listings and public UK water notes. No lab test. A qualifying purchase can earn us a commission at no extra cost to you.

Check the ban before you automate
Under the Water Industry Act 1991, section 76, a water undertaker can restrict hosepipe use. The Water Use (Temporary Bans) Order 2010 defines that use broadly. A dual-outlet timer on the tap does not create a private exemption. If a Temporary Use Ban is in force, a sprinkler or open hose on a schedule is still the kind of use the notice usually stops.
Some undertakers publish drip or trickle exceptions, with conditions such as a timer, a pressure-reducing valve, and delivery fixed to the soil. Thames Water’s wording is an example, not a national template. Recheck the live notice for your postcode. If the only plan is a spray pattern during a ban, change the method. Detail sits on the water timer hosepipe ban page.
How often each zone must start
United Kingdom reviews on the RAINPOINT ITV256 say each zone can start only once in 24 hours. That suits one deep evening soak. It fails a turf strip that wants morning and evening on the same outlet. The Johgee brass-inlet timer and the Johgee 326 list starts from 1 hour to 15 days. Insoma lists 1–23 hours or 1–15 days. The RAINPOINT IOB247-UK lists every 1–12 hours or every 1–7 days. Map the plant need, then match the stated interval.
Johgee units claim 1 second to 99 minutes. Insoma claims 1 to 360 minutes. IOB247 claims up to 3 hours 59 minutes. Stagger the outlets so one line gets the tap’s flow. If a bed needs three short pulses and the shortlist allows one start per day, discard that class before you open the table.
Keypad on the tap or a Zigbee hub
Five of the six kept ASINs are keypad timers. Control lives on the unit. No Wi-Fi gateway and no Zigbee hub appear in those titles. The SONOFF SWV-ZF2E Hydro DUO is a Zigbee 3.0 valve that requires a hub. United Kingdom reviews mention Home Assistant, Hubitat, and the eWeLink app. There is no large keypad screen on that unit.
If nobody will keep a hub online, or guests must change a run without a phone, stay on the keypad cluster. If you already run Zigbee and want schedules plus a flow meter, use the Zigbee water timer vs tap timer page. Rain delay is a pause you set, not a rain sensor. The ITV256 names a sensor port and a separate sensor.
Brass, washers and shared pressure
The ITV256, Insoma, and IOB247 state brass inlet and brass outlet. The best-value Johgee states a brass swivel inlet, and a brass outlet is not stated. The Johgee 326 does not state a brass inlet. Brass is not a leak guarantee. United Kingdom reviews on the brass Johgee still report drips at the brass-to-body joint. On the nylon Johgee, inlet leaks and short UK tap threads lead owners toward the brass-neck model.
UK ¾ inch BSP taps need a seated washer and hand-tightening. Pliers on a plastic collar are a damage path. The ITV256 lists 0.5–8 bar. Johgee rows list 0.05–0.8 MPa. Insoma writes up to 116 psi. Both outlets at once will starve each other on a weak tap, so stagger starts.
Rain delay, power and what to ignore
Most keypad units want AA alkaline cells that are not in the box. One Johgee United Kingdom review says high-capacity NiMH cells were refused. A low-battery shut-off claim is not a watched cycle before a holiday. IP65 appears on the Rainpoint pair and the SONOFF. IPX5 appears on Insoma and both Johgee units. Neither rating means frost-proof. Drain the unit and bring it indoors before a hard freeze.
Ignore any promise that a timer legalises a sprinkler under a ban. Settle ban risk, start interval, control class, and inlet fit before star order. Job-based picks are on the best 2 zone water timer page.
Common questions
Do I need a two-zone timer or two single timers?
Use one dual-outlet unit when both areas share one bib tap and you can stagger starts. Two single timers need two taps, or a splitter that still shares pressure. If the rear bed is on a different supply, two singles can be clearer than one shared valve.
How many starts per day does my garden need?
Count how many separate openings each outlet needs in 24 hours. One deep soak can fit the once-per-day pattern UK reviews describe on the ITV256. Morning and evening on the same zone need an hourly interval, such as the Johgee, Insoma, or IOB247 listings.
Is a brass inlet worth the extra cost?
Brass necks resist the collar cracks that show up on nylon models in this set. They do not remove joint leaks. Pay for brass if your tap thread is short or you have already cracked a plastic collar, and still pressure-test before travel.
Keypad or Zigbee hub valve?
Choose a keypad if you want on-unit control with no hub. Choose Zigbee if you already own a compatible hub and want app schedules and a flow meter. Do not buy the SONOFF expecting a large screen on the tap.
Does rain delay replace a rain sensor?
No. Delay is a pause you set for a stated number of hours or days. A sensor port, where the listing offers one, needs the separate sensor and still follows that listing’s rules.
