sps freak!
Where can I get 1.5" Vinyl tubing for a decent price? Or can someone tell me how to hardline PVC from a Glass-Holes 700gph overflow?
Thanks,
Kevin

Don't use vinyl, i don't think they make that big any how. Use Spa flex It is flexible PVC. you can get it at Lowes and it comes in 1.5". it is a bit pricey tho. if it s too much than I would hard plumb it. Its not to hard you just need to see what angles you'll need to use. I would use 2 45's for a 90 angle tho, will make the drain more flowing.

Vinyl tubing that big is a nightmare to work with - just go with spa flex.
Once you get the stuff from glass holes, take the bulkhead down to lowes and dummy fit everything while you are there so you know you get stuff that works. The bulkhead is probably going to be threaded - just find a PVC fitting that threads into the bulkhead and will take 1.5" spa flex. Depending on how you want to run your lines, you may need elbows or other fittings, so have some idea of how you want to plumb things before you go.
As for the 45 vs 90 thing... logically it makes sense, but I've read conflicting information from reliable/knowledgeable people in the DIY forum as to whether or not two 45s really do flow better than a single 90.

how much does spa flex run and what section of the store is it?

The coefficient of friction of water flowing through a 45 degree angle pipe, of the same diameter, is about half of what it is with a 90 degree angle. As well as, can't think of the law or what not, been awhile since I studied fluid dynamics, when water goes through a 90 degree angle it hits a flat wall and creates turbulence in the water that is flowing at the 90 degree angle in turn creating more friction in the 90 degree angle vs the 45.
Is it negligible and really won't effect the flow in our applications, YES. But the best advantage to using 45 over 90 is that you can use 2 opposing 45's to replace 2 opposing 90's which would make the friction gap between the two even greater. Also there is less chance of things getting stuck flowing through a 45 vs a 90 degree angle. Most municipalities even have laws against using a 90 over two 45's when plumbing runs under a concrete slab.
Thanks Dave for the complement.
Jackson, not trying to put your statment down just justifing why I use the 45's.

Absolutely. More information (especially when from a reliable source and/or supported) is never a bad thing.

alright I'm heading to lowes right now to check it out

I've decided to go hard line for the plumping to the sump and vinyl tubing for the return as the return pump has a 3/4" barded fitting

If anything you Don't want to use vinyl for the return to the tank. It is under pressure and the fittings aren't air tight. You will get salt creep/leak and some times air suction into the hose at the fittings over time. Also they are clear which creates more algae growth in the tubes. If you are hard plumbing the drain I would suggest to hard plumb the return. Since the pump is barbed I would suggest to just use a small 1 to 2 inch piece of vinyl to connect to a fitting that will go to PVC. This way it will be under water so you won't have any of the above stated problems.
Outta curiosity what is your return pump?
