What is the registered pressure drop at 20 gpm and 10 gpm?

Depends on how clogged up the filter is Stephen. Plus the pressure into your system means this variable can only be determined by measurement. I have pressure gauges that allow me to make some determination as to when the filter needs changing. The type of filter also determines the flow rate, 1 micro vs 10 micro. Rating depends on your needs, keep in mind static pressure remains exactly that.

I have a 5 micron filter in there. When it is new I do notice a noticeable drop in pressure on the cold water line. It's good on the hot water. Strange. It's about 10 lb less on the cold water line. Which I don't like. I used 3/4 copper pipe.

I did not notice any drop in water pressure at all, but I'm on a city system and my water pressure is actually to high! But I thing it all comes down to the filter cartridge, you use, the more they filter out the more restrictive, lowering your water pressure. Some filter cartridges filter out down to one micron and need changed monthly, may lower your water pressure. I use the ones that need changed every three months, and when they flushed our water lines, I had a lot of junk trapped by my filter. I also ran 3/4" pipe from the pipe interring the house to the filter before I tied it into my house system, which is using 1/2" pipe. No problems so far, I would recommend the Watts filter to anyone.

I have had no drop in pressure. I am on a well ,the filter is plumbed with 3/4 cooper pipe.

The pressure on ours is great! Not sure about the specific GPM, but I would not say it is anywhere near low flow!

under normal operation 2-3 psi and 5-7 hard running. i set my idle pressure at about 18 psi so it never drops below 11-12 psi. from what i read anything above 10 psi is safe for primaries. i dont know how high you can safely set it but i havent had any failures yet. hope that helps. note: i am using an edge guage system so the pressure drops are seen digitally on screen and measured from primary, correct or not.

Depends on the area of the country. But normally 10 to 11 psi.But read the instructions and following them.

I dont know. I gave up. It is about 1/20th of a regular pump, so 20x as much I'd say.

Mine came with a 20 PSI regulator. I got mine about a year ago. I had the same exact concern as you. The 20 PSI works like a champ.

I measured the GPM at 2.5. It does not have a flow restrictor that can be removed.

I'm not sure how much pressure you need but blow 10 lbs it doesn't seem reliable. I think I would look for a different source.

Look at Shurflo website. There is no difference in GPM or pressure setting. Have no idea why there's two different model numbers, but you could ask Shurflo. They should be interchangeable.

do you mean .12 and .20? 20 grams would go approximately five feet before dropping out of the air.

If the water pressure falls below 20 psi. the pump will cut off. You must maintain 30 psi. to 50 psi. when running to keep the pump on.

GPM is gallons per minute. It is the flow rate that the filter will process. The pressure drop is the lower pressure that is caused when your well water tank cycles on and off when drawing new water out of the ground. Make sure your pressure valve cuts off around 40 psi.

High and low pressure settings come pre set from the factory for a given range such as 20/40 or 40/60. That being said either of these pre set pressures can be adjusted by use of 2 pressure adjustment spring loaded screws. There is a limit to the adjustment so you should purchase a switch that is pre-set closest to the pressures needed or wanted for your system. Remember if your system has a bladder type expansion tank the air pressure will need to be reset in the bladder if you change the low pressure setting on your pressure switch. I hope this is beneficial.

Hard to say. I have a 1200 gph pump and it really flows and gurgles. Just ensure the pump discharge size matches the filter outlet. You can always install in outlet to bleed off excess pressure

Measured 1 gallon in 30 seconds = 2.0 gpm. I think my pressure is fairly high. Hot water did last longer than the old 2.5 gpm head which actually used 2.6 gpm.

20 feet - that is why the 20 is in the model number.I have seen a graph of its pumping ability.
