Need some opinions from expert plumbers. Our small, older house (1949) was completely re-plumbed a few years ago by professional plumbers. We have a 1" copper line from the meter to the house and then mostly 3/4" throughout the house. Only one bathroom. The flow rate in our bathroom increased tremendously once the nearly clogged galvanized pipe was gone. We enjoyed our showers like never before. Now, just last month, we remodeled the bathroom completely and installed a Grohe single lever shower/tub control to replace the three "dumb" valves (hot/cold/diverter) we had before. The Grohe PBV has a listed flow rate of 5.8GPM @ 80PSI. Our house has no where near 80PSI- I believe it's more like 35PSI. Our shower is now much less enjoyable (with same shower head) and the tub takes longer to fill. So given all this my questions are:
1) the valve has 3/4" fittings on it. The tub spout and shower pipes are 1/2". Would simply changing the pipe from 1/2" to 3/4" help to increase the "pressure" and flow from the valve?
2) If not, what would be the proper solution to this? Remove the PBV and install a thermostatic valve?
BTW, Terry, we are loving the elongated, CEFIONTECT Drake! Thanks bro. And thanks all for any input.
