Does this timer reduce water pressure from household pressure, for use with 1/2" or 1/4" dripline?
1394890
No. No reduction. I just turned my supply down lower for my greenhouse sprayers.
1394891
No, if you use it with a 1/4" drip line, you will need to include a separate 25 psi pressure reducer
1394892
No. This device is just an inline solenoid with a timer. You will have to install a small pressure reducing device behind the Raindrip for it to work properly with a drip system.

Not sure if it reduces the pressure but I actually use it with a 1/4" dripline and it works pretty good.

It depends on length of the run as well. Look online and there are good resources to help you determine if 1/2" is adequate for your job. I decided against using it at my house because I am in lightening alley in Florida and I did not like the pictures I found of appropriately grounded hose getting blown out.

I have 3 and 2 outlet timers, not a single outlet but I presume the programming is almost identical so the answer would be , no. It can certainly water for the duration of one minute but I think 6 hrly intervals is the shortest. Not sure what you intend watering but can only suggest you water at a very low flow rate to be equivalent to the amount of water you expected to use under your scenario. This may not be suitable but the simplicity and ease of use of these timers means intricate watering patterns cannot be addressed.

This works for me. I'm in the same situation as you have just described. Most electronic timers out there require certain amount of water pressure to assists the opening/closing of the valve, but this particular timer, Toro 53746, does not require any pressure at all to function. Hope this helps.

Good question. The pump was designed for the 1/4 in Try it and see, it will take you 15 minutes to find out, you will need to McGyver the fittings at the pressure tank and the faucet.Let me know. Mike

If you're talking about your sprinkler lines then yes (assuming 3/4" lines). I tested mine when we laid our new sprinkler system and the pressure drop is very rapid (5 seconds before you have to shut off and rebuild pressure). My lines are approximately 500 feet each station. Had to re-pressurize twice and any residual water after that is fine. As to the connector, it depends on your back-flow device. Mine is a Watts 009 series with 1/4" fittings. I used a quick change connector, 1/4" ball valve and a 1/4" hex connector. For the Watts, its check valve #4.

I'm not a plumber, but the PSI of any faucet depends on household water pressure. The only variable in the faucet itself would be a flow restrictor. I found no restrictor on this item.

Texas Skunk, I could not attach my Claber 8454 directly to the outdoor water faucet because the housing on the timer would hit the house when attempting to screw the timer onto the faucet. I chose to add a 3 foot water hose between the outdoor faucet and the timer and this allowed me to hid the timer behind a landscaping bush. My timer lays flat on the landscaping rock that surrounds the plants. The timer has worked flawlessly for the past two years. Hope this helps! Keith

I'm using one on my water tank but it does have a 1/4 hp pump on it. Works good. If you are just thinking about a water flow on this time I don't think it will work. I'm sure you have to have some pressure to move the timer.

Yes - that's what I used mine for. I put it on a timer so it only runs during waking hours. My water pressure is slightly below 70 psi and there are no problems.

it is 3/4 inch - You do have to use a few extra wraps of sealer tape. Now it does not go by a pressure so much as it does in reference to water flow. The switch on is a higher flow than switch off. The unit is a plunger type and is directional (you have to install correctly). It will not sense a drip - drip -drip but triggers at a low flow. Hope this helps

Please go to Melnor's website and download the manual for this timer. The average household water pressure is approximately 60 psi.

Both inlet and outlet are 1". Use a reducing coupler for the in, thats what I did. No setting for the pressure, there is only a pressure switch for on and of 30/50 psi.

The Hot and Cold connections for this valve is 1/2 inch The 1inch line will need to be reduced

I am not 100% sure. BUT I know that the outlet by the garden has so much pressure we've busted a splitter and a lead hose, yet the timer unit has been fine. We've replaced 2 valves that leak. The valves seem to open all they way, we do have a limit on how many soaker hoses we can feed on each one as it gets light towards the end. I am not sure this helps you.

I wouldn't recommend doing that. I bought the 1/2 inch diameter version for transporting the water to various areas of my garden. I then punch a hole for a 1/4 feed at locations where I want drip irrigation. You won't have enough water flow for multiple locations if your main transport line is only 1/4 inch.

This uses a standard 1/4" male pipe thread and must have full pressure to work.This will not work on a regulated low pressure output.
