Our shower diverter just started to leak (i.e., fails to divert 100% of the water to the shower). Is there a kit to correct this problem or do I ask Kohler to send me a replacement spout. I was just on their website and I beleive I have identified the spout from their current parts catalogue. I accidentally broke a hand-held shower from Kohler and they replaced it free under their lifetime guarantee program, so I imagine I can get another spout from them, too, as they have been very customer oriented. Lastly, if I need to replace the spout is this something a handy homeowner can do? Thanks in advance to all responses. Take care everyone and have a great holiday. George
