I have a 15 year old home(service call) that has an upstairs bath consisting of a bathtub with shower,toilet and two lavatories side by side. The bathtub/shower has a delta 13-14 series pressure balanced valve. The bath/shower unit has great volume and pressure and maintains great flow even when you flush the toilet. The toilet has great volume.
The water pipe in the home is pex. I found 3/4" pex feeding from downstairs to this bathroom. The cold pipe reduces from 3/4" to 1/2" at the toilet with a 3/4 x 1/2" x 1/2" tee and continues to the lavatories with 1/2". I cant see anything past the toilet connection. It disappears into the 2x12 floor joist.
The lavatories have low cold flow. You can turn the hot water on either lavatory and it will literally blow water out onto the floor with the aerators off. The cold is the problem. One lavatory will run "ok" volume but way way less than the hot......if you turn on the second lavatory cold only and have both running at the same time the flow drops to a trickle between the two.
If you turn on the hot water and cold together on one of the lavatories and then only the cold water on the second lavatory the hot water has so much pressure it backfeeds through the faucet into the cold line and boosts the cold water at the second lavatory.
I'm thinking a kinked pipe or foreign object lodged in a fitting between the toilet connection and the 1st lavatory. All the fixtures are lined up on one wall.
The supply to the toilet has super pressure and volume with the supply running into a bucket. The problem is with the last two fixtures at the end of the run. The fixtures are on a 12" wall in a line all side by side.
I'm thinking cut the ceiling from below between where I'm getting water and where I'm not getting water and cut the pipe........
Any ideas?
