Does this timer reduce water pressure

Not by a noticeable amount in my application. I expect it has a ball valve, so depending upon the size of your supply and demand, it may restrict the flow a little but if you have a typical hose bib this is not noticeable.

I have high pressure in my home water lines. I don't know how high, but it has always been so high that cheap timers fail quickly. I bought two of these more expensive timers and one lasted only about 4 weeks; the other is still working. One reason I liked these timers is that instead of shutting off quickly and causing water hammer effects (which also fatigued and broke a brass Y fitting), these shut down slowly so no hammer effect. Overall, the one that still works works well. The other one stopped working. A pretty expensive failure.

Yes. The steamer automatically shuts off when the water level gets too low.

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.

No, it is not a water timer. It measures flow and total usage in gallons and liters. Works very well. Difficult to figure out how to change from the default liters to gallons but once you know, it's great.

I have purchased two of these filters for two seperate showers. The second one I ordered came with a water flow restrictor ring which was an optional use feature. I used the ring on the second shower and now wish I had one for the first as well. Overall I would say the filter alone does not reduce water flow and if it does it's minimal.

I honestly don't notice a water flow reduction - and if there is one it is not close to 1/3. I have owned this brand/model for many, many years (I am currently using 5 of them) and when one goes bad I definitely notice the reduced flow rate. For me, the convenience of having these timers far outweighs the infrequent problems that I have with them.

Yes it does. Once it reaches the set pressure it turns off. Turns back on when pressure drops.

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

There are 5 settings for Timer control,they go as follows.1.Unit works continuously. Automatically stops when water level drops too low.2. Unit works continuously for 2 hours and will automatically stop.3. Unit disperses for 5 seconds and rests for 40 seconds.4. Unit disperses for 15 seconds and rests for 50 seconds.5. Unit disperses for 30 minutes and rests for 15 minutes.

did not seem to reduce water pressure or flow, did not notice any restriction

Yes it has a little sensor that shuts off the unit when the water level falls below it.

The timers I've received are time-based. There is no relation to volume through the filter. Due to that I employed an alternative method for determining replacement timing. When the water volume was noticeably reduced I would order a new filter. That seems to be the wisdom of the other answerers too. For me that was 40 months last time and saves lot of money over the recommended 12 month replacement cycle. Your experience may differ.

As the timer moves toward the shut-off point on the timed cycle, the flow of water is reduced gradually so that the shut-off is not sudden, causing a sudden pressure increase in the piping network of your house.

it doesn't seem to reduce pressure.... and yes you still have water during the backwash. I assume its not filtered. I have a dual tank softner that delivers filter water during backwash process

I am almost certain the answer is "no". It turns valves on and off, and has no way of sensing water pressure, etc.

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.
