Digital Hose Thread Watering Timer

A:  Yes

A:  The only limitation would be if there isn't enough clearance between the timer and the house. I installed mine remotely attached to a metal stake and connected it to the hose bib with a short hose.

A:  You can connect a hose end timer like our BO9D/BO9DB to a standard frost-free hose bib without issue but be aware some frost-free hose bibs have built in vacuum breakers and these frost-free hose bibs will leak constantly if you connect a hose end timer (tap timer). Make sure your frost-free hose bib does not have a backflow preventor (vacuum breaker) built in to avoid leaking. If you have any other questions, please contact our technical service/product support team at 1-800-322-9146.

A:  As long as you have a standard hose thread connection, you should be fine. I hope this helps

A:  Yes but the timer itself still needs to be removed if temperatures are expected to get below freezing.

A:  The risk of back flow is very small excepting natural disasters etc. If you wish to comply with ordinances which may apply you would need a separate back flow preventer. The valve stays in the last position signaled (on or off). For example, if the battery dies or other circuitry fails while the valve os open it will stay open and vise versa. I suspect most users don't use a back flow preventer and very few experience ill consequence. L Dexter

A:  I have never had a problem with these

A:  You do need a back flow preventer. They have one you can buy for the kit.

A:  No back flow preventer

A:  Not sure. I gave a backflow on my faucet.

A:  This is not a backflow device! So if you have no pressure in your domestic system and there are connected hoses in your irrigation system above the elevation of your hose bibb or a vacuum in your domestic system backflow could occur during the timed watering periods. Consider adding a plastic PVC check valve rated for under 30 psi and backflow would be unlikely.

A:  I have 4 of these and I have found that there is no backflow problems at all.

A:  Unless the timer is higher than anything on the line it's feeding, I'd add a back flow preventer. The back flow preventers are cheap and I've learned the hard way that they are a good idea, even when you don't think you'll need them.

A:  No back flow preventer

A:  The BO9DB does not have a backflow preventer so one must be added to your head assembly. We recommend using our model D45 hose tread back flow preventer installed after or downstream from your timer. If you have any other questions, comments or concerns please contact our technical service/product support team at 1-800-322-9146.

A:  Up to 24 hours, if that is what you select.

A:  each program can be set to run 12 hours, so if you used 2 programs, you could run it for 24 hours.

A:  The BO9DB hose end timer will allow you to program up to four different start times within the same day and the run time can be programed from 1 min, all the way up to 11 hour run time. If you have any further technical questions, please contact our technical service/product support team at 1-800-322-9146.

A:  I use mine 6/8 hours at a time. I use it for misters on my chickens

A:  We water orchids with four on-off cycles per day and the batteries last approximately 1 year. The valve draws power only briefly when switched on and again when switched off. How long the water is on should be irrelevant.

A:  No problem. Attaches to any hose fitting thread.

A:  If you have high water pressure your hose may burst. It happened to me once.

A:  I found another solution. My faucet/spigot combination is too inaccessible to connect the timer directly. I found brass goose neck and Y splitter parts that took care of that problem without using a hose.

A:  Should be fine, but I wouldn't just let it lie on the ground, but that's just me. Perhaps you could attach the inlet hose and outlet hose to a post with the timer unit in between. There isn't a way to mount the timer unit to a post directly.

A:  The BO9DB is designed to be installed directly on an outdoor faucet or a faucet y splitter, it cannot be installed on the end of a garden hose. If you have any other questions please contact our technical service/ product support line 1-800-344-1172.
