I know this topic has probably been tackled before, but...we're remodeling both bathrooms in our home and the low pressure is really noticeable, especially in our new showers. These are water-saving units, but there's just no "punch" to the shower, if you know what I mean. We have well water here. What kind of pressure boosters are out there...and what kind of expenses am I looking at? I'd appreciate any advice.

What kind of well pump and what is the pressure of the cut in and cut out on the pressue switch.

Typically it is 30-50 psi or 40-60 psi.

Code requires a minium of 40 psi, but but in most cases with the pump running you will have much more than 30 psi with water running.

The first thing I would do is to look for restrictions. Filters and water softners are the first to check. And do you still have an galvanized steel pipes in the house or from the well?

If you need a booster you can get packaged systems like these.

Bill sorry to inform you not all codes require 30 PSI

For example many of my accounts are high rise buildings exceeding 40 stories in height so to get 30 PSI up to the water tower or even just to the uppermost floors would require NYC to have a water main pressure of 290 PSI (neglecting friction losses)

It would depend on which codes one is following and then take into consideration the piping materials as copper tubing is subject to erosion if the velocity is above 8 FPS (3 FPS) H/W

NYC code requires a minimum of 8 PSI at the fixture fully open , we both know this will not operate a flushometer this is exactly why the morons who keep insisting on a one code does all have no clue as engineers do not get out of the office enough. The plumbing "engineers" really need to evaluate who they elect to represent them (IMHO)

I hardly think death valley and Anchorage Alaska and NYC and Rhode Island have the same designs factors such a frost levels and earthquake and population considerations

This was a house on a well.

The next time I see a 40 story house supplied by a well I will get a copy of the NYC plumbing code .

BTW. I do telemetry controls for water distribution systems. One monitored a system on Lookout Mt, TN. By the time the pipe got to the bottom of the mountain it was almost at 1000 psi.

Another town was as flat as a billlard table. And the pipes where old and in bad shape. Had the keep the whole town with 5 psi. Too high and pipes started going. Too low and the irrgation sprinkers wouldn't work.

And some places in the northern states don't have storage towers. Rather VFD pumps are used that are staged and ramped to maintain pressure that far ends of the lines based on flow curves.

If you had to deal with 1,000 PSI what piping materials did you use?

I once had to use RED Brass schedule 40 piping Plain end no threads and used TP copper and brazed all the joints and that was for a domestic water supply well below 1,000 PSI

My work ends with the software to do the monitor and controls. So I never saw the installation.

But I understand that they used SS pipes with flangeds and welded.

I understand that the people that installed the controls where REAL Nervous working around that much pressure.

Want to know nervous?

Try being a 17 year old in the Navy in a boiler room working with 1,500 PSI super heated steam NOW that's scary.

Or

Being in the sub basement of a building looking at a 10" Clean out knowing the entire soil line is blocked and your the low man on the totem pole to open it
