  • clear hose connector
  • 5 feet water piping with connector
  • sewer hose

Update:

So many people were asking how to make the water line with connector that the company started making them. You can get the TankTool here

This method works best if you have a straight line to your black water tank.

Step 1

add clear connector to hose

Add a clear straight hose connector to your black water sewer hose. You’ll want to be able to see what’s going in and what’s coming out while you’re working on the clog.

Step 2

clear connector

Drill a small hole in the top of the connector to add the 5ft water line. Make it at an angle so you can easily push the line through. Also make sure you use the same size bit to make the hole as what the diameter is for the line. This needs to be snug so there isn’t any spillage coming out from the hole.

Step 3

water going into tank

Start pushing the line into the hole on the clear connector. Once you start pushing it through, open the black tank valve so you can push the five feet of water line all through to the back of the tank.

Step 4

pull hose back until you find the plug

Once the line is in the black sewer tank where it needs to be, turn on the water. If no water starts to come out after 30 seconds to a minute, then you know your line is behind the blockage. Slowly pull the line out a few inches at a time and pause for a few seconds after pulling out until you start seeing stuff come out.  This lets you know that you’re at the blockage.

Step 5

stay in area when stuff starts coming out

Stay where the blockage is for a bit. The pressure of the water line should help breakup the clog. Start moving the line out further to keep breaking up the blockage. Keep doing this until you have the water is freely coming out all along the tank.

If the clog is near the toilet:

If your clog is at the part where the toilet pipe meets the holding tank, the you might need to push a hose through the top to get rid of the blockage.
