sewer valve

I took my 2000 Roadtrek 190 Versatile to a local repair shop because the grey tank started to leak at the valve. It turns out that the bracket on the pipe that the valve is attached to is broken. Any ideas on how to replace/fix this? The repair place said they are not sure where to get the part...

Replacing my gate valves for the black and gray water lines in my '04 PW Excel TD (Ford). Black is a 3" valve with 48" cable. Is the gray a 2" or 1-1/2" valve with 24" cable? And any advice on the project (including parts brands and vendors) would be helpful. Thanks!

Hey all, i got this trailer last fall, so i have yet to use it. I had to do some repairs/maintenance items to it upon reception. I went through the process of flushing the black water tank via wand down the toilet and managed to loosen quite a bit apparently... When i took it to the dump...

Does anyone else notice this - If I use my regular sewer hose and not use the macerator, the macerator hose will fill up because there is no valve to separate the two after the main black water valve. Then I will have to use the macerator anyway to clear the hose!
