Ok, so most of us use PVC pipe. It's inexpensive and easy to work with.
If you need guidance on how to install pvc pipe, we can help you with that.
Then there's areas where you may need a flexible hose and the best thing for that is schedule 40 flexible PVC. It's totally compatible with all standard schedule 40 ridgid PVC fittings and also the primer and glue. It comes in white or black. I like the black for inside the pond. It's less noticeable.
Both standard PVC and flex PVC can be buried if you like.
I personally have all my plumbing within the pond and bog, so if anything leaks, no water can escape the system.
Don't waste your money on the common corregated "pond hose". It wont last very long and you'll get frustrated with constant leaks.
Try to incorporate a means of easy disconnecting of your pipe/pump for winter removal or general maintenance. The best thing for this would be a union.
Second choice would be a rubber Fernco coupling.
Ive already installed some simple pvc set ups. I know the simple use of it but for a pond is it any different, meaning anything I should know , tricks , tips ect..?
