Hello My Name is Toxsus,..........
And I am a pumper. :)
I just got my home aid pump together yesterday using a Mighty Vac II and a gravel cleaner. I didn’t have any padding so I could only pump up to about to about 5 Hg, but once I had a good seal it was pretty easy to maintain. Anyway all in all it was very inexpensive to make and twice as easy to put together.
