I went to HD and listened to a nice sales pitch about PEX. The pipe itself
seems to be a good idea. Then I found how much the connectors (sharkbite)
cost and about wet myself. Compared copper + cheap f/f coupler, versus pex
+ expensive sharkbite. Came home with a load of copper pipe.
Seriously, are those things lined with gold? Copper may not be cheap, but
holy crud the cost of sharkbite connectors for what I am doing would have
cost more than all the copper I bought. And for a job this small, it's not
realy worth buying the tool and pieces parts to make my own connectors.
Maybe next time I'll consider pex. Maybe when the price of connectors comes
Sharkbites are a bit spendy bit they;re quick and easy. You can rent
a PEX crimper or an expansion tool.
PEX connections can be completely made up (expansion style) faster
than cutting and cleaning copper....forget the sweating.
Hell....if oyu pay the shipping I'll rent you my hand expander for a
I was / am pretty "old school" about a lot of stuff, I agonized of
the choice of copper vs PEX. My PEX re-pipe is coming up on 3 years
now, no problems. I'm glad I used PEX, only four joints per fixture.
And it snakes great through an old house...minimal demo.
I used the home run design. So I have minimal joints.
I dont know the layout of oyur plumbing system but 1/2 copper can
carry a fair amount of water. I'd guess the problem is not the
tubes / pipes.
And an additional point - the economics of PEX have to be looked at as a system
- and that includes labor, not just material. If a two man crew can plumb an
entire house in a day with PEX, but sweating copper would take a week, paying
more for the material makes sense.
Do other water devices in the house have good flow? Garden
hose, fill the mashing machine, sink, etc?
You didn't mention what type of pope. Galvanized is noted
for closing down, but PVC and copper less likely.
As a quick and easy test, I'd suggest to take the shower
head off the angled pipe. Turn the water on, and see if you
have good water flow. It won't be very good for showring.
But, it will help with the diagnosis. Others have suggested
ways to clear a restricted shower head.
i had a similer problem with pressure and it seemed the hot was not so
hot even with the heater turned up beyond recomondations ... turned
out a rubber gromet piece inside the valve on the hot side behind the
mixer had broken off and blcoked more than half the flow, the mixer
slowed down to componsate .. one of those no scald valves
