I am planning to use spa flex, where is it available? I want something super simple for my setup. I am planning on having the overflow drain to my sump and have the water return to the tank, nothing fancy. I just want to make sure I get all the materials needed. Another question I have is how do I attach the spa flex to the return and overflow? Do I use clamps or..??

Thanks

The spa flex can be glued into standard PVC fittings. You need to use the proper solvent cement though. You can probably get the proper stuff at most spa shops. Western Pump on 42 ave SE has it for sure, as well as a great selection of pvc fittings. The regular cement will not hold as well on spa flex since it is too hard. The proper cement has some flexibility to it once cured. Might as well get some of the proper primer too just to make sure it holds.

Are you planning on using the spa flex for the return as well? If so there will be a lot of drag in the line, unless I'm confused with some other product. Flex pipe has all of the ridges in it, no? Anyway, can you let me know if Western Pump has everything you need, I'm thinking of switching my drain to Flex to cut down on sound.

Spa flex is smooth on the inside.

If I were to use PVC instead, what parts will I need? remember, I want to keep things SIMPLE. Also, with the PVC, do I glue the pieces together? Do I physically glue the PVC part right on the bulkhead? If so, then how do I take it off if I plan to make some revisions in the future?

PVC has to be glued together. You can use couplers to allow for removing pumps etc for repairs and maintenance. Usually the bulkheads have pipe threads, so you can remove the threaded fittings from them if needed. There are bulkheads that are slip fit (glue together) also if you prefer that method.

Thats what I'm trying to figure out right now.

You cut it and then cement in new pieces.

That's what couplers are for!!

If you are completely new to sumps, are you aware of any of the precautions to avoid floods that you should take when installing and external overflow?

normal PVC Cement and primer works fine of flex SPA pipe. mine has been holding for 3 years now and still strong, just make sure you do the primer and use a medium or heavy body glue.

I am not using the CPR overflow. The tank is drilled for an external overflow.
