Pride Plumbing came out and provided a cost estimate to perform the following work: 1) turn off the water to the affected chase; 2) remove a malfunctioning faucet valve from a toilet; 3) use copper ProPress fittings to replace the toilet's water supply stop for a new Acorn control valve; 4) install all off the new Acorn control valve parts; 5) turn the water back on and test leaks; and 6) make the appropriate adjustments to the control valve.
