mk1gti Posted June 15, 2019 Share Posted June 15, 2019 Hello, I recently purchased a 1982 Toyota Dolphin and have been using the toilet the past couple of weeks and took it down to empty the black water tank. When I got there I was not able to find the dump valves, just the hole where it drains and what looks like a rubber block or something that keeps the tank sealed. Below is a photo the the area I am referring to. Hope someone out there is able to help me figure this out before I have to take it into an RV mechanic and drain it there and install some different hardware. https://photos.app.goo.gl/AjaJWE4fB3J5zCak9 Thanks in advance!

Odyssey 4x4 Posted June 15, 2019 Share Posted June 15, 2019 Looks like they broke it and jammed a screw in there to keep it sealed. There should be the relief handle where the screw is that you pull outward and the system will drain. It shouldn't be that hard to repair, maybe a bit smelly 💩 Quote Link to comment Share on other sites More sharing options...
WME Posted June 15, 2019 Share Posted June 15, 2019 Can you pull on the screw?? Maybe vicegrips Quote Link to comment Share on other sites More sharing options...
Maineah Posted June 15, 2019 Share Posted June 15, 2019 Yeah I agree looks like they broke the handle off. Quote Link to comment Share on other sites More sharing options...
darrel Posted June 15, 2019 Share Posted June 15, 2019 Make sure you have a sewer hose connected before you attempt to pull on that screw-bolt. If not stand back. Darrel Quote Link to comment Share on other sites More sharing options...

jjrbus Posted June 16, 2019 Share Posted June 16, 2019 I seem to recall the pull handle shaft being threaded for the handle, so makes sense that the gate valve end is threaded also. So pulling on the bolt might open the valve. Just don't try it in the driveway! Quote Link to comment Share on other sites More sharing options...
Maineah Posted June 16, 2019 Share Posted June 16, 2019 It is very difficult to get the horse back in once the gate is opened. The head of the bolt turns inside the gate valve so it's normal for the shaft to turn. Quote Link to comment Share on other sites More sharing options...
Gulfstream Greg Posted June 16, 2019 Share Posted June 16, 2019 It could be in the open position! Quote Link to comment Share on other sites More sharing options...
