I've had a frustrating two half-days digging out my old plumbing tools to try and fix a tap. The taps they put in for our washer do not have washers, and cannot be repaired once they develop a leak. But the tap was soldered directly onto the copper pipe, and there was no shut off valve! It took four trips to the hardware store, and three different tries to come up with a solution. I think I finally have it fixed with the magic new shark-byte taps that don't need soldering. It seems to work, and doesn't leak, but it turns on the copper pipe. I just don't trust it not to leak! I think I should have just called a plumber!
