Plumbing Recommendation

"You may have a bathroom you do not regularly use.  Maintenance could be as simple as flushing the toilet or turning on a faucet once in awhile." Roger Peugeot, plumber

I have pondered whether I own the house, or it owns me.  Maintenance, without the capable help from my husband, is overwhelming.  Painting trim, doing all the outside work, moving heavy objects.  Even hanging a picture on the wall recently sent me into longing for his help.  He was so capable, before he got dementia.  How do you cope?
