Cleaning Maintenance Question

[Tspors58]

I have a 210g w/two overflow chambers on backside. This system is 15 years running, FOWLR. My sump filtration is in the basement

Curious if anyone ever shuts down system and pulls out the 4 overflow pipes and cleans them out? Cleaning inside of overflow?

Good / Bad / Potential Issues? Or are somethings better left alone.

Thanks

It would be a pretty big project. Personally, I wouldn't clean them. Replace them instead. WAY easier!

After 15 years there will probably be a good amount of buildup

i have done that in the past, on my 400gallon tank. I also completely drained my sump at same time to redesign the sump layout, had return pump being shut off for 10 hours, no problems with entire procedure.
advise. start early in the day, in case pipe breaks or leaks and you have enough time to run to store and get replacement...
