Braided Nylon tubing
 

I bought a sump pump to try out although it is extrmemly loud currently.

I noticed that it reccomended using reinforced braided nylon tubing or better especially on the inlet side of the pump due to the possibility of collapsing th e tubing.

Those of us that are using high GPH pumps out there. have you had any issues with your tubing collapsing due to the suction of your pumps?

I plan to eventually get a 1000+GPH pump for my multip comp rig and I am a little worried that this high of volume of water could actually erode or damage standard vinyl or plastic tubing.

I have never heard of an issue with tubing collapsing. Have you considered a reservoir? Also, I don't think that sump pumps are meant for 24/7 use... For a multi computer cooling system, have you looked at the MD20RZ? It has ~7m of pressure, and will probably maintain a fairly high flow rate through most things you can throw at it.

Actually I am probably going to try out one of the Gen-X pumps

The one that is supposedly the equivalent of that Iwaki you mentionedwas just curious if anyone had any issues with tubing collasping on them.

then again this sump pump I got can still do 62 GPH at over 40 feet


Probably just the fact that it creates a heck of a lot more suction than an aquarium/pond pump is all.

Nylon braiding won't keep the hose from collapsing as it's just as soft as the tubing.

The only thing it's good for is to keep the tubing from blowing out from pressure. And don't think for a second your pump is capable of enough pressure to blow out even regular tubing. Your radiator is going to blow apart before your tubing does.

If you are genuinely concerned about the suction side flattening out, look for wire reinforced suction tubing. Linky

But on the other hand, if your tubing *is* flattening out, you seriously need to rethink your loop because you have some major restriction somewhere. And your pump is probably cavitating like a mad man.
