After you get the toilet out it becomes pretty intuitive. Bring your drill for taking out rivets and do not drop the hex nut caps on the inside bathroom wall. Putting those back will be "an interesting exercise"
! Once you start you will see that some panels may over lap the box. You will also need to remove a plastic strip to get the rivets out from the top/front of the toilet tank box.
After all of that is done...is your toilet in good shape?
You will need a new rubber ring an maybe a new mount....mine was in bad shape. I did a new toilet as well. If you get a new one get a good one, the cheap ones seem to let many people down at inconvenient times.
Try not to mess with the plumbing below the floor unless you have to
. That plumbing is for grey water. I does not flow into the tank. It goes out the same hole as the black water. You need a blue boy under these at all times.
If you still have the old tank and it leaks don't fool with it. Get a good replacement and a new valve. I have an Inca replacement and I have heard good things about the fiberglass tanks. There are great threads on installing the tanks and valves.
Good luck...oh yeah....get plenty of medium & long aluminum 1/8 pop rivets...not Olympics, just regular pop types, an extra drill bit doesn't hurt.
Before I forget...if you have a model that has a wardrobe opposite a gaucho, you may as well remove the shelf from the wardrobe. You will need to access some of the wall to replace rivets when you are reattaching the abs plastic wall liner.
My one piece of advice is go for it
! Get a maintenance manual...
...you can look up what little you won't actually figure out on this project. Start with the toilet....then get the abs plastic top off of the box. You will have to loosen a few things up to do that . Just tug a bit you will find the spots. After that lift up the plywood that sits on the tank. Then get underneath and disconnect the valve from the rest of the plumbing. If you like it can come up with the tank. Before lifting the tank out, get into the wardrobe or the wall access from the other side. You will be able to see the tank. There are three wires connected to the tank. Disconnect these, then disconnect the dump valve control; you can now remove the tank (I think
Read a lot of the plumbing threads! The advice of others got me through it...hunting down the tank was a job. The two I found that seem to have good results were Inca plastics (built the original) and I have heard good results about the fiberglass tanks that Andy sells. Be very careful when measuring valve and inlet locations. or do the cuts after installation...if you don't know what I am talking about, it will become obvious when you pull out the tank. You will need to align the outlet with the plumbing that is attached to the outlet.
Have fun.... personally I am glad it is over with
, but it really was not a bed job once I got going. Best wishes for a smooth job. I'll check the thread regularly and if you have questions as you go I'll try to help, there are a number of us that have done this job ONCE! meaning that we were rookies at it like you are ... at the moment.
