I have a friend in San Bruno who runs his entire house with a Shurflo Extreme Blaster which pumps approx 6.5 GPM at 45PSI which gives you plenty of
volume for showers and everything and he opted for a 12 volt system, even though they have 120 volt power, since they have frequent power outages on
the grid, which results in no water outages.
I have a 120 volt pressure pump with an 18 gallon bladder tank and have set up a 12 volt system as a backup for times when there is no power. I use
a simple battery charger on trickle charge to keep the 12 volt fully charged all of the time. In my old place we used solar power so we used the 12
volt system all of the time. The smaller shurflo pumps usually produce about 3.5 gph which was always a little light but when I went to the 6.5 then
I had more than enough volume for everything.
Bob Frambes is right on with the pipe size reccomendations. Stay with the largest size you can for flow and velocity. 3/4 carries almost twice as
much as 1/2 and 1 inch is even better. For hot water make sure to use CPVC or copper, and the new polybutelene flex pipe can handle both and is great
to work with but needs banded and compression fittings.

your Shurflo Extreme Blaster takes 10-15 amps at 12v and cost ~$200
with an inverter and a 120v pump you would use 7 amps and have a bigger pump...the cost ~$400
of course the amp use is ONLY when the pump is running and with a pressure pump the pump runs less often thus taking less energy
that shurflo does look like a nice pump...
i really have problems using plastic pipes in permanate applications like a cabin...maybe just "old fashion"...
those compression fittings with CPVC sometimes leak and pressure DOES change from time to time...
i like solder...

I found the pump for about 175 I think at http://www.rivermarinesupply.com
I too like copper, but have become sensitive to copper in a lot of uses in the house when I started to do the testing for our little water
association. When the water sets for the night the first dose in the morning has a pretty high copper content. The real problem though was lead from
the old solder joints that was really screwing up the water quality and the lead content was really high, so we had to replace the plumbing on several
houses with PVC to get things to pass.
I installed a sears 1.2 hp shallow well jet pump with a bladder pressure tank and will probably use the shurflo as a backup. My friend uses it all
the time and keeps a rebuild kit on hand should he ever have problems with the pump part. He tried the new variable speed and it was a disaster so
Shurflo exchanged the pump for a constant speed and it has worked like a dream.
