I put the 2 pumps in as you suggeted. Only difference is I have all 1/2" lines. But it worked greaaaaat!!
The shower stayed at a nice constant, both in heat and pressure. This will hold me over till I get the hot water heater situation figured out and re-plumb the whole thing.
Just for a little more trivial info........
I bought one of the "Oxygenating shower heads" that are supposed to be so good and save lots of water, but I'm afraid they must work better with city pressure. It worked just fine but, I did not think it was "all that and a bag of chips". (definitely not worth the 40.00) I also have one of those little chome jobies, that look like a little megaphone, and it seems to work pretty good too. It shoots out water more like a mist. I have not compared the amount of water used by both of them yet, but my guess is the little chrome one uses less, possibly a lot less. The "oxygenating head" is supposed to save you water but that might be compared to a hose.
lol Just kidding, but I'm pretty sure the little chrome one saves more. The only drawback was rinsing your hair. For some of you, that may not be a big deal (no disrespect, just sayin
) but your wives might not like it. It took me a little longer as I have hair (from my head!) to about 3" above my belt. Stuck in the 70's, I guess.
Just thought I'd give ya an up date. Thanx again,
