I have a two story home built in the 70's. Water pressure is excellent everywhere in my house except one shower. I've tried
- replacing the shower head
- removing the shower head, and letting the goose neck soak in oil/vinegar/cleaning solutions
But neither of these has increased the water flow/pressure to the shower. When I turn on the water with no shower head on, the water flow/pressure coming straight from the gooseneck is just as weak, so it seems to be "in the pipes".
The piping is in my attic under plywood, and under a "double studded" joists set-up so damn near impossible to trace/follow. What do I need to do to increase the water flow/pressure to this one sink/shower?
The issue is with both the hot and cold water, for both the sink and shower in the bathroom. Seems like I have one of two options
- Run a new line from the crawlspace hot water heater to the upstairs master
- Get into the attic and see if I can locate the piping and find the issue
