Good, high quality kit. Installation is straightforward and easy. Some tips: get Rectorseal sealant before you start for the new orifices. Orifices are small and the valve body they thread into is difficult to access with your fingers while holding the orifice. Solution: put the orifice on a toothpick to facilitate applying the sealant and to get it started into the valve body being careful not to leave wood particles in the orifice. The provided wrench is inadequate; use a 7mm 1/4" drive socket on an extension with ratchet.
