If you’ve got good water pressure in one place even with a water restrictor, then you’ve got good water pressure in general, so this means it may be a different problem.
The first culprit to check, of course – is still to see if your second shower has a water restrictor. It may be a different brand of showerhead, one of the kinds that have two water restrictors rather than one, so that’s a possibility.
If you’ve checked this, and it either wasn’t there or you removed it and the problem is still there, then you’ve got a different problem (yes, there are a lot of problems here). Something else is affecting the water pressure in your second shower, and here are some possible reasons, and possible fixes:
- Start with your showerhead; check it to see if it has a great deal of lime or mineral deposits clogging the showerhead holes. While you’re at it, check the little screen and washer inside the showerhead fitting for the same thing. If either contain minerals, soak them in vinegar overnight, and scrub them out with a stiff brush.
- Check all the supply water valves to that shower, see that they’re fully opened.
- If all else fails, it could be a blockage in the pipes downstairs, and it may be time to call us in to diagnose and fix the problem.
If you’ve checked all of the above and none have fixed the problem, it may be time to change the way you’re taking a shower. You can do this by:
- Installing a high flow (2.5+pm) hand-held showerhead that comes with a flexible hose; you can do this and still keep your regular showerhead; the hand-held can be used for the rinsing issues.
- Change the showerhead to one designed to push the water out faster by pressurizing it; they’re often called “amplifying” or “pressurized” showerheads. Unfortunately, if you have one of the popular large “rain-shower” type showerheads, they have a great many holes that are generally larger as well. While they look wonderful and – with enough water pressure – are great, they also disperse so much water so quickly that they actually lower water pressure. You will be happier with one of the amplifying showerheads designed to capture water first, and build up pressure by funneling it through smaller holes so that the water comes out at a good steady pressure. These work well.
