Will these valves allow full water pressure? Or do they restrict the flow of water like single hose timers?

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 measured the pressure and flow on both sides of the valve. I saw no drop-off in pressure or flow with the valve open.Peace,Jason

Actually there is a slight pressure drop , however, even though water pressure is not so high in my area, It can generously feed four sprinklers in each line.

Yeah, it restricts flow nicely in my experience. I have it right behind a large, 5"-wide showerhead that has too much flow by itself. This little valve is great for adjusting the flow to my or my wife's preferred pressure.

Not a 100% sure but do not think would work with static water source. It seems to need good water pressure to work effectively. Have noticed that it works best if I open the source valve all the way

Thank you for the question. No that is not the case, the trigger can be in the off position while the water is on at the faucet and the hose will NOT burst.Of course, that is assuming normal domestic water pressure.

You can certainly T-off and run the timer but the pressure would be determined by the pressure you have on your line to begin with and the size of the pipes you use. The timer would have no bearing on that. The timer has standard hose sizing. Running 4 lines on one output will substantially reduce your output on the lines, to 25% on each line. Simple math. If your lines are of a smaller guage then you will not have a problem. Reduce the pipe size for their output (you can do this and maintain a good sprinkler system) and it will still work.

No. There is often a flow restrictor that can be removed to give more pressure if your water pressure is low.

I used this valve in a shower, where you typically don't control flow volume, only temperature. Not sure if it has other intended uses.

Interesting question. I think you are asking whether the timer opens a pilot valve and then line pressure opens the main valve, or whether the timer opens the main valve. It is my impression that the timer opens the main valve and thus it would work with low pressure - but I may be wrong. I have actuated it when it was not connected to water and I heard it click. But that could have been a pilot. I stopped using mine since it stuck open one night, neighbor called me, and I had to drive to my cabin in the forest to turn it off. Easy way to find out - buy and send it back if you don't like.

It does not restrict flow. It works really well to turn off water when hot then pull the chain and full flow begins. It was simple to install and I have used for a few months with great results.

No. All you need is a pressure control valve or faucet valve that is designed to withstand the pressure if the water goes directly to it.

I have no idea what flow restriction diameter is but if you try to do this off of a water utility I don't think you will have enough pressure.

Yes. It decreases water pressure to both, but they will work at the same time.

It is just like a kitchen timer. It only does "on" and "off." The rate of flow through it depends on how high you turn on your faucet. It is all up to you! I love these; I have saved soooo much water with them. The only thing to remember is to take them off in the winter or a hard freeze will break them--plastic, you know. Here in So. Calif. I often need to water in the winter, so I occasionally forget and lose one in a hard freeze.

water pressure is primarily governed by your available pressure at the source. if you have strong pressure going into the panel then the inherent panel's restrictions are not very noticeable. i have had the unit for 3 months and it has not clogged nor have i noticed any decrease in pressure from the day i installed it. remember, this is a 'rain shower', not a pressure hose. when the valve is fully open, there is more water flowing than any previous shower i've had. but it is no a 'jet'. it produces lots of 'water to rinse'. incidentally, many communities near us will not approve this installation on new housing due to amount of water usage. hope this helps water pressure is primarily governed by your available pressure at the source. if you have strong pressure going into the panel then the inherent panel's restrictions are not very noticeable. i have had the unit for 3 months and it has not clogged nor have i noticed any decrease in pressure from the day i installed it. remember, this is a 'rain shower', not a pressure hose. when the valve is fully open, there is more water flowing than any previous shower i've had. but it is no a 'jet'. it produces lots of 'water to rinse'. incidentally, many communities near us will not approve this... » Read More water pressure is primarily governed by your available pressure at the source. if you have strong pressure going into the panel then the inherent panel's restrictions are not very noticeable. i have had the unit for 3 months and it has not clogged nor have i noticed any decrease in pressure from the day i installed it. remember, this is a 'rain shower', not a pressure hose. when the valve is fully open, there is more water flowing than any previous shower i've had. but it is no a 'jet'. it produces lots of 'water to rinse'. incidentally, many communities near us will not approve this installation on new housing due to amount of water usage. hope this helps « Show Less

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.

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.

Of all the timers I've tried (4 or 5 different types - both mechanical and battery-powered) these restrict flow the least. I don't remember doing a direct comparison between straight hose and this timer because a straight hose connection without a timer was pretty useless for me. :)
