Our main bathroom tub/shower has the original Price-Pfister fixture from when the house was bult in 1965. The unit has the seperate hot and cold valves and a tub/shower diverter. We are having difficulty being able to balance the hot and cold water to a comfortable temperature. It dosen't matter if you turn on the hot water first or the cold water first, it will take several attempts and wasted water to get the water just right. I have replaced all 3 valves with new ones that I purchased directly from Price-Pfister. That didn't help. We recently purchased a single handle Delta unit from Lowe's hoping we could upgrade to a newer unit, but the original unit is nestled in between the studs and putting in the new one would require cutting studs with out damaging the tile wall. At this point we are prepared to hire a plumber and go ahead and install a new unit, but I thought I would see if someone might know what the problem is so we can keep the original unit and avoid a costly upgrade.
Thanks in advance,
