Different RV Waste Water Systems

Firstly let me say that all RV waste water systems are different, and I only have experience of ours, however I wanted to share, because this is a problem we encountered when we first got our RV motorhome and is is also a problem we overcame. So I will share what worked for us. Depending on the exact problem with your waste water tank it might not work for you, or you system may be a little different, however this is a good starting point before you spend money taking it to an RV repairs specialist.

We have a CI Carioca. Our waste water tank has a handle to pull to release the waste water. I believe some RVs have a button to press however providing you can get at the pipe that leads into the tank it should still work.

Help - The Water Is Not Coming Out The Waste Water Tank On My RV Motorhome!

The problem:

Our problem was that the tank was full, and we were pulling the handle, but nothing more than a tiny trickle of water was coming out! We summised that it must be blocked, although we weren't sure.

We took it to a specialist, who was able to help us by telling us what we needed to do to sort the problem, although we got chatting to him and he was kind enough not to charge us! He told us that this is a common problem and he sees it all the time, AND, it is really simple to fix!

Here is what he said. This is a common problem when an RV motorhome has been winterized, stored and not used for a period of time. The plate that opens the waste water tank can become stuck and silt etc can block up the opening preventing the water from being released. This is just where it hasn't been used.

To Fix The Blockage In Your RV Waste Water Tank

To fix this problem there are 3 simple steps:

  1. Pull the handle to your tank firmly in and out several times to unstick the plate.
  2. Get a hosepipe and put it up the pipe that leads to the tank and blast water IN to the tank. This will remove any blockages.
  3. Finally use a little bit of blue chemical in the waste water tank. This is NOT something you would usually do as blue chemical is not for this purpose. However as a strictly ONE OFF, for fixing this problem the engineer said it is OK. Always check the rules of your campsite as many places do not allow you to empy blue chemical at the waste water disposal point. Instead you will need to empty it at the chemical toilet point.

These three simple steps should solve the problem, however if your problem persists take your RV to a specialist.

Tips To Prevent Blockages In Your RV Motorhome Waste Water Tank

  • Never allow food waste to go down your kitchen sink into the waste pipe.
  • Especially avoid letting pasting water go into the waste tank, this is really bad as the starch in the pasta can become like glue.
  • Don't wash boots in the sink.
  • Avoid getting anything gritty, muddy or solid into the waste water system.

Follow these tips and keep your waste water system happy!
