water pressure

 The is an old house with old pies.  There is little water pressure even when you run 1 thing at a time, like the shower. any advantage to changing to CPVC in the basement where we have access? Can't really get to the ones in the walls.

It is very common for old pipes to have calcification lining the walls (like arteriosclerosis).    As a consequence, flow to showers/sinks etc will require replacing all the pipes.   Plumbers do this routinely and usually it doesn't require destroying the walls.   Call a couple for an estimate.

Hopefully by now you have done something about this.  You actually have a water volume problem and not a water pressure problem.  In this picture you will see why this is so. 





Strong recommendation to get all of your water piping changed out to copper and make sure the plumbing contractor insulates both the hot and cold water pipes.  They should be using American made type "L" copper pipes and fittings. 
Do not recommend pipe restoration.  This is a process where the existing pipe is restored from within by a method of epoxy injection.  From experience, I have found this process to not yield the results that homeowners are informed about.  Please see the few pictures below

If its an old house with galvanized pipes, than it's like my dads arteries.  You can check your pressure at a hose bibb outside, with a static pressure gauge.  If your pipes are cloged then go with a product like Pex or Wirsbo.  Comes in rolls and installs in a flash.  You can rent the tool to crimp the fittings on.  Plus this stuff can expand up to 600%, great for cold weather climates.  Good Luck

Check the pressure from the city. If it is good you need new pipes. If you have your own well check the pressure at the pump.

I would bet you need new pipes. The new CPVC lines are very good. Make sure they are code in your area. They are not in my area so we had to go copper.

If the pipes are clear, you can also see if a device to increase your water pressure would help. They look like a pressurized plastic barrel that has a rubber/neoprene "bladder" that pressurizes water before it is sent through the pipes. They featured it on ask this old house recently  http://www.iptv.org/series.cfm/10773/ask_this_old_house/ep:705 I think they said it cost about $400. Check out the link.
