Hey we are stumped. Went to take a shower in master bath (just a stall) turn on water nothing came out, toilet sits beside of shower it fills when you flush. Tub in corner has water, double sinks in front of shower has water both hot and cold, just nothing in the shower stall. Where can we start looking for the problem?

First unscrew shower head and see if water runs through shower arm ( pipe shower head mounts onto ) without shower head installed. If it does than clean shower head ( or get new one ). If it doesn't than the problem is the cartridge inside the faucet. Here, you will have to remove and replace the cartridge. If cartridge is the problem than come back and one of us will guide you with replacement procedure.

Back to you. Milo
