Shower Plumbing help please?

   / Shower Plumbing help please? #21  
Remodeling showers is a big part of what I do for a living. Every year, I install just about every one of the major brands of shower valve assemblies and I've never seen or heard of a valve that was low flow. Granted, when you take out the plastic cartridge inside the brass body, the holes that the water flows through are rather small, but they are all very similar and with decent water pressure in the house, plenty of water gets through those openings. House should be between 40 to 70 psi with 60 being about ideal. How much pressure do you have at your house?

The shower heads where messed with by the government for awhile, but lately, they seem a lot better. Five years ago, clients would just through them away and use the old ones regardless of how ugly they where. I have one client that has a collection of at least 15 shower heads. Before that, you could drill them out and they worked great, but the government caught on that everyone was doing this and the manufacturers had to make that impossible. If it is a brand new shower valve assembly, odds are that the shower head is probably OK.

Others have mentioned this, but I'll say it again. When you work on plumbing, you risk breaking off debris that has built up inside the pipes. Once you get everything connected, that debris needs to be flushed out. Worse case is having to take out the valve, clean it real good, put it back in, plug it up again, take it out, clean it again, and keep doing it until you get everything. Then take off the shower head, clean it, run the water without the shower head, and then put it back on again. Some houses are a lot worse then others, you really never know until everything is done and it's time to test it before getting paid.
