Anyone ever check their pipes?

[slapshot]

Looking at the picture it appears you have a lot of long run horizontal pipes. It is best to avoid long runs like that. It allows material to build up very easily. If their is no way around to avoid running your pipes like that it would be beneficial to instal an inline filter which will help keep you pipes clean. You can get one cheap at Home Depot and all you would need is course sediment filter. Just a thought from an old pipe fitter. The closer to the pump you put it the cleaner the pipes. You can plumb a bypass loop that would allow you to change filter without shutting the pump off also. If you get the parts I would be glad to swing by and help you out! LMK

Thank you for the offer, but I had very little horizontal pipes before I replumbed. The pictures are from a section that was vertical and 3 feet from the pump. I have a filter on the intake of the pump, always have.

Was the build up in both the drain and return plumbing?

Just the return, my drain if flex and I typically shake it, maybe that keeps it clean
