All parts can be purchased at Lowes or Home Depot for around $50 or so.

Parts
1- Bucket Head Vacuum
2- 5 Gallon Buckets
1- 5 Gallon lid ( screw on it optional but very handy )
2- 1 inch PVC Compression Coupling ( the threads are unique to this part and you will need to purchase the second one for the extra nut).
1- PVC Cap to cover intake when you remove the hose. ( update. I found a better way. Use a short 1" PVC pipe, around 2 or 3 inches and cap off one end. you can push it into the coupler and tighten it down. Side note- in my case o used some sand paper and cut the diameter down just a bit so i would not have to fight it going on install.)
12 inches or so of heavy duty string to tie your loose pipe to the bucket handle so you don't loose it while not in use.
