Yes! I have a feeling of pride and accomplishment today! We have been having trouble with the taps in the main bathroom upstairs (main floor of the house). They were very expensive when we bought them 5 years ago, and yet they started leaking a few weeks ago for the second time. This time my mom couldn't fix them. When I was in Edmonton for the wedding, I went to Home Depot to find the little replacement cartridges, but they don't stock them. So my mom phoned several plumbing supply places until she was put in touch with the manufacturer of the taps. Since these are high-end taps, they have a lifetime warranty, and the company sent out 4 cartridges for us.
The cartrudges arrived in the mail today . . . the same day that my mother left for Denver for 2 weeks (for work and vacation). So I had a dilemma: either figure it out myself, or leave everything for my mom to fix when she gets back. I did it myself! I did have to call my mom for some guidance, but I am quite proud to say that we have normally-functioning taps in the bathroom that no longer leak. Way to go, myself!
This just goes to show that a good woman can do anything herself . . . well, except for get pregnant. That definitely takes two.
