Great news.
Got the shower water valve replaced (real bugger to get the old one out - Moen - shame on you), got the hot water valve on the sink fixed.
Don't know what it is with her, told her water would be off today, so she says she's got to get her 1 hr walk and a shower in first. So I get to start at 10:30. She goes to the store - favorite passtime. She does ask if she can help and my response is always 'sure - go to the store'. Well, done anyway, daughter will be happy with hot water when she visits.
