I have a well that feeds my house through a 1" black poly pipe. I have recently moved my pressure tank and I got all new poly pipe and installed it. I did this job 3 times already in 2 days. Im using those gray plastic elbows and metal hose clamps. After the first time, I had leaks. I tried everything to stop it but I couldnt. So I took it all apart, cut the ends again and this time heated the pipe so i would slide on easier and maybe form to the elbow. Didnt work again. So I tried it one more time. This time I did the same as last but I also heated the pipe a little while it was on the elbow and then tightened the clamp. It still leaks horribly. What am I doing wrong? Is there a trick to this? I have an irrigation guy coming tomorrow morning to fix it unless I can get it fixed by myself today. Any advice would be appreciated.
