Ok peeps. I picked up some spa flex in Hudson today and am starting to plumb things. I've got some questions:
1) The megaflow directions for installing the bulkheads just say to wet the rubber gasket. Is that enough or should I get some teflon gasket stuff?
2) The directions say not to glue the drain assembly. Should I glue the return pipe (the elbow at the top)? I'm assuming the pipes aren't glued into the bulkheads so you can remove things later if need be; i.e., they are just pushed in tightly.
3) What do I use to go from the bulkhead barbs to the spa flex? What I'm reading is that it's not a good idea to try and put the spa flex over the barbs. (Don't think I could do it anyways... it's damn tight!)
4) The picture below is my (dry) attempt at the return pipe line. I have 4 lines from the tank to the basement: 2x 3/4" return lines (only using one), and 2x 1" drain lines (using both). I need to figure out from the barb(s) to the spa flex:
Is the T- at the bottom going to cause any issues? I'm using the union under the T- just incase.
The bottom of the union would be connected right to one of the return lines (spa flex).
Any input on this part is appreciated. It will also answer the same questions for connecting the drain lines (spa flex) to the barbs there.
5) What type of cement should I use on the spa flex? I have the regular OATEY clear/purple primer pack. I'm reading that I should use WELD-ON or something else. Opinions?
6) On the drain lines I'll be installing BALL VALVES in the stand and down in the basement. Am I missing any other valves, check valves, etc.?
---
Under the tank will be very clean: the T- for the two return lines, two drain lines, and whatever power cords for lights, etc. The four spa flex lines run from the tank/stand through the wall, into the basement, and just past the AC duct-work. From there I will switch over to standard pvc.
I'm open to direction for anything I might be missing. Like, should I make the hole in the wall/floor bigger? It fits the 4 lines now, but what else might I want to run down to the sump in the future?
Thanks all! (Getting excited for some water!)
