Well, HomeDepot just got a crimping tool, two rolls of pex, one red and one blue and a bag full of sharkbite fittings back. Much thanks for sharing the lessons learned.
One question though; I'll be replacing 3/4" main to 1/2" branch ID hoses. Have you been able to maintain good pressure at the faucet with 3/8" throughout?
Again, many thanks,
Mort
Mort,
A large majority houses in this country are plumbed with 1/2" copper and street pressures are often in excess of 80-90 PSI. Our house is "pressure reduced" to 100PSI and our 1/2" copper lines will peel the skin off your back in the shower while washing a load of laundry, flushing the toilet and watering the lawn all at the same time.. Just took a shower while watering the lawn with my wife doing the dishes all on 1/2" line.
Most boat pumps are set at below 40PSI so 3/8" is more than enough and far easier to plumb. The most flow restriction I have ever seen comes from small micron water filters not from using 3/8" line. 3/4" is way overkill on a boat as is 1/2" but 1/2" is much more reasonable than 3/4". Even if there was some noticeable restriction that is never a bad thing on a boat when dealing with only a fixed amount of water on-board.:nerd:
