PVC cleaning

[M_norrick]

Not certain I am in the right area or not to post this so please forgive me if I am not. I have a 300 gallon system that consists of one sump with 4 tanks (180, 29 Tall, 30 gallon frag tank, and a Refugium. The big system has been running for approx 4 years now and doing good except my flows to the remote tanks (29 gallon and frag tank). When I first fired it up, I had too much flow and I was forced to pinch off on the discharge of my 2 iwaki 30rxt’s (one to the 29 and the other to the frag tank). Now I am having issues with lack of flow. I have cleaned the pumps with no improvement. I suspect my pvc is getting full of tube worms or some kind of other creatures. I would simply replace my pvc if I could but unfortunately it is behind 4 year old drywall in a finished basement. Any suggestions on how I can remedy this without another remodel? Thanks in advance.

I wish that would work. My pvc is about 20' in length behind a wall. I guess I could modify this tool to work though.

Take a look around, it’s basically just a pipe snake. Many many different models and lengths.

Not sure how many unions you have, but i would be installing unions in the setup so you can service the pipe in sections. With unions you can remove the parts thats not in the wall to outside and use high pressure hose. Then you only need to snake part in wall. Jmo.
