Q: Iβm redoing the bathroom in the back of my 40-year-old house and want to replace the present toilet with a tankless model.Β Do I have to increase the water pressure in the house to get it to operate correctly?
A:Β No, you might actually need less water pressure than you already have.
Generally, these units operate at less than 65 pounds per square inch, a level that is probably the maximum found in most houses.
You can do the pressure test yourself using a pressure gauge from a hardware store. But in making an installation like this, you probably need to have a plumber verify what your pressure is and compare that to the manufacturerβs recommendations.
