We have a bathroom in my parents house that, for the majority of my life, has super low pressure and my dad has spent years trying to figure out why and how to fix it.As I know literally nothing about plumbing I'm curious what I can look into to even get an idea of where and how to get started.
>>2953337could be too small a feed line, like half and inch run all the way from the mechanical room for the whole bath
>>2953337Map out the plumbing first if you know the sizes of the pipes and what couplings there are. Any plumber could tell from just a drawing what the problem is but there are calculators online too for head loss.
>>2953337have you replaced the shower cartridge and faucet?
>>2953337Is it just the shower or every fixture in the bathroom?>>2953416This is a good start. Address the fixtures and see if they are reducing flow or are clogged.
>>2953337id do >>2953395 and check for any problem angleif you cant see the piping without destroying your home id try using an autopump to keep pressure up
