Good day everyone. Forgive me if I make any errors as this is my first post. I have a 2 year old Hayward Heatpro heat pump 140k. Very cold winter in Georgia. When i went to turn turn off the water bypass, i heard a strong leak in the bottom. The pvc at the very bottom is cracked. Of course, I saw a post from 6 years ago but the website stated the info was too old and I had to start a new post. This is such a simple parts repair for pvc but Hayward states they have to replace the entire exchanger for $2K. The PVC parts by themselves cannot be any more than $50. Is there anyone out there that has experienced this and can share what they did to fix it? I can see that i can cut the bottom pvc straight pipe and simple put on a new elbow and connectors. But I don't have any part numbers or specifics. Please see the 2 pictures as the crack is located at the "X". Thank you for your assistance. Scott.

Welcome to TFP.

You think you are limber enough to cut and glue PVC at the crack area without removing the heat exchanger, then go for it. What do you have to lose?

What part numbers are you looking for? That should be standard Schedule 40 PVC with an 90 elbow. Cut it out and remove it. There maybe parts numbers on the elbow.

If you need to remove the heat exchanger to fix it, then you need an EPA 608 certificate and the proper tools to evacuate the refrigerant before it can be disconnected.
 
Thank you ajw22. And you are correct, what have I got to lose. Gaining access is the toughest part. I have never worked with pvc before. I am fairly hand in every area of repair activity. What glue do you recommend? And how do you feel about using hose clamps as well. The crack is actually a 6 inch long slit. Thank you
