Low Water Pressure Issue in Shower - Real Plumbing

We got a call about a low-pressure issue in a master bathroom. This house was a new construction home a couple was looking at buying, so they wanted to make sure the home they were going to buy was ready to move into with no issue whatsoever. Let me know how you would've handled this troubleshooting plumbing call.

What do you think about this low pressure issue? Do you think I was right?

[michaellinner]

Finally a man who understands the difference between flow and pressure.
I've been searching, in vain, for information about which commercially available shower heads are easily modifiable to increase flow.
Every single video I've come across on this specific subject confuses flow with pressure claiming that they are the same thing. In this instance they are, for all intensive purposes, opposites.

If you've got the low down on that information I would love to hear it. That would make you my hero for life. Although this video didn't address my specific problem I'd hit the thumbs up button a thousand times if I could.
I sincerely hope this reaches you and that you might respond.
Thanks in advance.
Help me Obi-Wan, you're my only hope.

Our new house had low pressure on all the faucets except the garden outlets.. The fix for us was removing the restrictors in the new energy efficient faucets. Made a very noticeable difference.

Really liked how Quickly you found the problem and came up with a solution, you are truly a professional Rodger, keep up the good work!

The building standards these days are trash. Feel sorry for the person buying that junk as their home. You can tell the low build quality alone just by the install of the water heater and how they finished the drywall. Shamefull

Pressure is fine at the tub faucet, it is only low at the shower head, even after soaking the head in CLR for a few days. This is a new issue in a 20 year old home. Would you suggest a cartridge change?

Don't even care about the pressure issue no more he put on foot booties love it when the repairman does that hate the ones that come to my house and wants to walk on my nice carpets with big dirty boots👍

It seems like the pressure gets lower sometimes. I know the fire station cleans out the pipes periodically.

[jacksplumbingvideos]

There is alot of galvanized pipe in my area I usually see galvanized pipe and it’s packed with rust causing the low pressure.

If you live in an apartment complex....should you still try and fix water pressure?

[geralyngoss]

I am looking for information on how to decrease the pressure in the shower. any advice on that?

[danieldawson]

What we have here is a failure to communicate!

[tdtfear]

I have a ceiling leak what should i do

[uaintplumbinguaintnothing]

I disagree that it's just that pex valve being the issue. My question is, is that house on a home run system? ( headers) or is it just teeing off from a branch line?
My guess is that fixtures are just teeing off a main line instead of a dedicated line to each fixture.
I also would of check the size of line coming in after the meter. Maybe it got reduced down to ½

[realityblooms]

Wow look at that truck. Can’t believe they make American cars that big. It’s a house, then they complain about gas lol.

[privatename]

I've seen guys put left over paint down them tubs

[thereefaholic]

Up-size yes but most of the fixtures and rough ins only have 1/2 inlets.

[JLitt-usvs]

Great video👍 i just did the plumbing in my mothers bathroom shower and i ran everythjng 1/2” copper to a kohler 3way diverter and temp valve at the instruction of kohler and now i have low water pressure in the raindrop showerhead and the wall showerhead… any ideas? Also i spoke to kohler and already took out the flow restrictor in the temp valve at their instructions…

[MikeSmith-ersz]

Those corrugated flex connectors at the water is not a professional install, although very common

[say_goodnight]

Love your vids but that one pex ball valve isn't the in any way close to the low flow problem, and even then the water heater itself acts as a reservoir to keep adequate volume on the hot side. More than likely they have undersized hot trunk, or there branches run way to far from the trunk if there isn't any scale problems at the fixtures
