why my new bathroom mixer valve have very low water flow?
I have bought the Italiano square thermostatic 3 way mixer diverter (B013), and I have recently installed it, I realized that the water flow is too slow coming out of it, I have a water pressure pump, but because of the slow water flow, it doesn’t keep the pump running constantly! is there any solution for this, please help!
I installed a bathroom on a second floor. A pressure pump was in the basement. Risers to the bathroom were all 3/4" and 3/4" was plumbed directly to the tub mixing valve. The shower had a mixing valve, a separate diverter valve that went to a hand held hose and a fixed shower head. Plumbing lines had to be bushed down to 1/2" to enter the mixing valve.
The tub has a lot of flow and always works great. The shower has never worked well due to too little flow. Even after a new regulator on the pump pushes pressure up to 70/55 psi (cut off/ cut in) There is too much resistance in mixing valve and too little flow into the mixing valve. The solution and yours is to re plumb it using a mixing valve that will accept 3/4" lines coming in. The problem is insufficient flow (amount of water) and not pressure.
