We have a manufactured home that was constructed and fitted out in Canada, although we live in Arizona. The home is approximately two years old.
I recently bought a Speakman showerhead at Lowe's and attempted to replace the original showerhead with it. Disaster! Using considerable force, I was only able to screw the new showerhead on a couple of turns. When the water was turned on, the connection leaked profusely. I had also wrapped the threads of the pipe with teflon tape as a sealer.
After giving up on the idea, I replaced the original head also using teflon tape. The showerhead screwed only the pipe effortlessly,threaded on fully and didn't leak.
Luckily I didn't damage any of the threads. But this makes me wonder if plumbing fittings in Canada have different thread standards. By merely looking at the pipe and showerheads I cannot see a difference.
Your input is appreciated!
