I have a 2nd story bathroom with 1/2" PEX running directly to the shower mixer from the 3/4" supply manifold downstairs (maybe 20 feet away). I installed a bar sink on the opposite side of the wet wall and installed a tee fitting with cinch clamps to tap into the 1/2" PEX lines that are supplying the shower (these branches will supply the sink when it is plumbed and are about 17" long but not in use yet). After I installed the branches in the 1/2" shower supply lines, I noticed a large pressure drop in the water coming out of my shower head. Does anyone know what would cause this? Are the tee fittings restricting flow to the shower? I also notice a loss of hot water after just a few seconds of running the shower. Could it be an obstruction in the line? The branches I installed in the 1/2" shower supply are about 18" below the shower mixer. There are no pressure or hot water issues at any other faucet or shower head in the house. Any insight is appreciated!
