tubing

OK, let's try to be scientific here, since we're talking about a bunch
of money. If my pump specs recommend 1.25" diameter tubing for the
distance I'm pumping, won't the friction on the tubing ID be great, if
it's got the spiral texture? So, to my mind, smooth tubing would be
much better, assuming I won't need to take any tight bends, so no
kinking.

With smooth tubing, clear PVC from Home Despot at 1.25" is expensive!
I don't need vac tubing at all. I could hard pipe with rigid PVC but
soft would be easier. Has anyone used the black tubing used for drip
irrigation? Seems that should hold the pressure. Maybe I should just
call my pump company hotline (Oase). What does pool tubing go for?

Thanks again. There's a big hole in my ground yawning to be filled
with water!

What length of tubing do you need? If the tubing is $1.50/foot, and you need 20
feet, that is only about $30 (and that is on the high end, IMHO). If I remember
correctly, I paid about $0.60/foot for the tubing I used, and I bought 10 feet
of it. So I spent $6.00 for the tubing for my pond. I don't see that as a big
expense. What you saw was more likely clear Tygon tubing, which is expensive
because it is pharaceutical grade. I found clear vinyl tubing for about
$0.64/foot at the link below:

So 20 feet of this tubing (1.25" ID) would cost you less than $13.00

Now, if you want to go with high pressure braided vinyl tubing, it does get
expensive. The plumbing store advertises it at $4.81/foot. But of course, that
is food grade tubing. I don't think you need to use that kind of tubing, do
you? I would shop around

I can't quite figure out the tubing thing: many sites recommend the
black spiral tubing, but in my mind, the ridges will inhibit water
flow compared to smooth tubing. I need 1.25" tubing. Is the
spiraling stuff really the best way to go? It seems expensive...

Thanks in advance.

Rob... as you have seen from the various posts there are a myriad types
of tubing...

To your question the black spiral tubing I've seen referred to the most
is "no kink" tubing and it is virtually smooth Inside... the spirals
are on the outside.

Now if you are using this tube on your suction line the spirals will
also help keep the tubing from collapsing from too much suction... it
is not as tough as PVC/ABS but much easier to work. Even if you choose
not to go with this you will probably need some sort of rigid or
semi-rigid tube for this purpose.

If it is for the out-put from your pump then any polyester reinforced
tube will be fine...barring really odd conditions the water pressure
alone will keep in the right shape.

Thanks for your message George, but that link you posted lists 1.25"
ID tubing at 3.19/ft. That's expensive at 20', no?

Look at it again. It is sold in 5 feet increments, so 1.25" ID tube costs $3.19
for 5 feet. That breaks down to about 64 cents per foot. This is the exact
type of tubing I use, and it didn't cost me all that much (although I only
boughyt 10 feet of it). Like I said, you should shop around for the best price.

My experience with clear tubing was that it algaed-up inside because of
sunlight and reduced my flow drastically, but as long as you buried it and
covered any part of it that is exposed, it may be alright. That is why I
went to black - algae problem solved , then I went to the "ribbed, anti-kink
black hose when it came out to solve the kinking, flattening problem where
bends or runs under rocks
