the perfect diy pvc overflow/melting pvc

i have two tanks that sit right next to eachother so for an overflow i just have pvc conecting the two as an "over flow" well, i didn't want to use pvc cement and air kept getting in through the conectors so i made my own bent pipe. i took a length of pvc and put a cap at one end. i then filled the pipe with boiling water and put the cap on the other end, waited 30 seconds for the pipe to get soft then bent the pipe to fit. you can bend it in any direction. its really cool. it takes a bit of gentle force but it works well.
oh use hevy gloves. the pipe gets hot.

I have heard of folks bending PVC before. I've also heard of folks using sand that had been heated in the over. Their claims were that the sand provided more internal support and kept the PVC from kinking during bending. Have any pics of your final product? Would be really interested in seeing the results! How sharp were the bends you made?

Neato! What size pipe you used? Do you know if one kind bends better then another (ie grey vs white vs black)?

well i dont have any pics(no digital camara) but i like the sand idea, cause i did have a bit of trobble with kinks. it would be easier if you had a form to bend it on. but the sand seems like it would be more of a hassle, heating sand in the oven and what not. i dont know if color makes a diffrence but ive done it with 1/2" and 3/4" pipe. it should work with all sizes

ive heard you can fill it with sand and just use a torch or maybe even a heatgun to bend it

Dont they make flex PVC? I thought I saw this stuff in the home improvment stores. Its for bending around small obstructions at the job site for like sinks and stuff.

the issue with most "flex" tubing is the ribs built into it's design to allow it to flex. The ribs cause major resistance to the flow and defeats the purpose of bending (at least for our intentions).

ok maybe flex was the wrong word. Bendable is more approprate. This is not the flex hose that you can twist and turn in all kinds of directions. This pvc looks just like regular pvc except you can bend it. It has a dark grey color vs the white of regular PVC.

I love PVC. If I'm ever stranded on a deserted island, I want PVC and duct tape.

I'd rather have food and shelter but to each their own


FF: ahh, then I'll have to look for it next time I'm at HD (or the new Lowes they just build in my area) I may have to take another stroll through HD, just to see whats new... haven't done that in a while. However, today probably isn't the best day to just say "hey hon, i'll be home from work late tonight, just gonna wander around HD for a little while" hehe. I might get in a little trouble.
