CPVC manifold question

So I built my manifold for my MLT out of CPVC. I started cutting slits in the bottom of the CPVC for draining with a hacksaw(PITA). I cant seem to get the slivers of plastic shavings off the inside of the pipe. I've soaked in hot water and used a hot brush with out any luck. Any suggestions?

 

Take a dowel rod or something equivalent and ream them out from the inside by quickly sliding the rod in and out. (That response was not intended to sound dirty)

 

Got a shotgun? A 20 gauge bore brush on a cleaning rod will do the trick quite nicely.

 

I rolled up a piece of sandpaper and passed it through. I also used a razor blade knife to clean up the slits before using the sandpaper.

Using a dowel or the shotgun cleaning kit is probaby better but I didnt have those.

 

just got my parts... $14 bucks may build this sunday. sorry to bring a thread back from zombie land but best place to post will post parts list & pics

 

With these first few words, I was hoping for some kind of hillbilly deburring technique using a shotgun.

 

I used a bunch of course pipe cleaners, it took quite a while to get it done. But it was worth it as I am still happy with the results even 2 yrs layer! Good luck!

 

If you buy a wood dowel that just fits inside the CPVC pipe and place it inside before you cut the slots there won't be many burrs when you remove the dowel.

 

Now that is a piece of wisdom!
