Hi folks
q.Is there anyway to increase psi to a single location ( new shower install )
perhaps an inline pump system for hot & cold wihout additional holding tanks?

If you have a PRV on the system, it will provide more pressure if it is not already maxed out.

No and it would require TWO pumps if there were.

Are you on a well system? City water? current static pressure? Pressure while a bathtub is running? There are a lot of variables, and you may have an entirely different issue. Insufficient pipe size can mimic low pressure in situations where higher flow rates are required.

I almost asked you, in your other post, how many gpm you had available for the car wash.

We need more information about your water supply, before we can advise you on pressure for a multi-function shower.

HELLO to the respectable folks!
my system is supplied by well, my pressure at connection piont to the thermostatic valve is at 50psi via 3/4" PB witch I will be replacing with 3/4" pex.
In addition I've ran a second pair of 3/4" lines to valve location, to boiler room so if I had to add some type of secondary pressurized system for only those two lines.
Note: Boiler rm is quit large should be ample room if additional pumps & tanks were needed to achieve adiquit pressure.
THANKS FOR YOUR TIME & input to you all!!!!

Archie....That wasn't meant as a shot. Those type of multi-head showers are commonly refered to as carwashes, and available gpm is very important. Best Wishes

I guess I HAVE OFFENDED EVERYONE OUT THERE!
THANKS FOR HELP TAKE CARE ALL!

My personal choice if I was requiring the kind of pressure and volume that you require would be to have two pressure tanks for your well system. Also, I might change out the pressure switch to a higher set point, such as a 60/80 switch. The tanks I would pressurize to 70 psi, and 60 psi. Normally I wouldn't set a tank at the low limit of the switch, but in your case you would be dumping water at a high flow rate out of the system, and the tank set at 60 psi would just empty as the well pump engages. Hopefully the well can supply water faster than your shower can drain it, or you could have a problem. 50 psi is plenty of pressure, but as fast as you will be draining the pipes, you could have a sufficient pressure drop. That is why I would change the well switch. Having 2 pressure tanks should take care of the volume problem as long as the pump itself can supply more gallons per minute than the shower requires. If the pump can't supply more water, set one tank's pressure below the low set point of the pressure switch so that when the well pump kicks on, it will feed as much as it can, and the lower pressure tank can pick up the slack by adding the excess volume required. Of course if the second tank runs out, you will get a pressure drop, and will probably be down to ice water anyhow.

A well that is undersized may not provide enough waters, from the ground, to allow for enough gallons per minute. Water pressure, could be another issue. Are you in an area that would allow for a larger pipe well, should you require it?
