The black tank flush on my coach stopped working. Apparently this is a common problem, if the flush nozzles get gummed up with crud or water calcification.

One of the members of my Tiffin Allegro Bus 2016-2018 Owners group on Facebook did a post about fixing theirs, which was very helpful. So I embarked on this adventure too.

The hardest thing is getting to it. I needed to remove this panel from the side of the coach:

The right side is easy enough, with a couple of brackets and screws easily accessed with the adjacent basement door open:

But the left side was tricker, with no door there, so I needed to insert a screwdriver between two panels. To protect the paint, I wrapped the screwdriver shaft with painters tape:

Then inserted the screwdriver to reach the four screws:

That done, I was able to remove the panel:

The fresh water fill hose limited how much I could move the panel:

So I disconnected that too:

My little folding work stool was very helpful for this operation:

Let’s have a look around, since I don’t get to see this stuff often. Here’s the black tank; the green circuit board is the See-Level tank sensor, and the yellow rectangle is one of the two sensors for the rear toilet (the other is above that, obscured by wires):

To the left of the black tank is the gray water tank:

Below both waste tanks is the fresh water tank; the pipe in the foreground is the overflow and vent:

Pipes and wires from the bedroom and rear bathroom:

The horizontal-ish pipes are for the central vacuum system:

On the other side of that wall, a vacuum inlet and hatch in the adjacent compartment (we don’t use this vacuum; preferring to use a cordless stick vac):

Anyway, to business. Here’s the culprit, the “No-Fuss” Flush:

I removed it from the black tank; a bit gunky:

Cleaned up somewhat:

I tested it, but it still didn’t work very well, so I drilled out the holes a bit more (on the bottom and sides):

That solved it; the holes sprayed nicely.

To re-mount, I used plumbers putty to seal it:

And re-mounted it (the water is from testing it):

Then just a matter of re-attaching the fresh water fill hose and re-mounting the coach panel.

All better now. Hopefully I won’t have to do that again any time soon, but it wasn’t particularly difficult, other than removing and re-attaching the coach panel.

Jenn didn’t like the bathroom faucets and soap dispensers that came with our coach, as the faucets were rather splashy, and the dispensers let water into them, diluting the soap.

So we bought replacements from Home Depot, and I installed them.

Here’s the old faucet in the rear bathroom:

The new faucet:

Looking under the sink, one can see manifolds of hoses to various parts of the bathroom (sink, toilet, shower, and washing machine); the sink hot and cold connectors are on the top:

This being an RV, of course the hose for the faucet was non-standard, so I needed to get a “hex nipple” to adapt the 1/2 inch MIP hose connectors:

Disconnected:

The old and new faucets:

A new hose, with the hex nipple adapter on the left, and the adapter that came with the faucet on the right:

Similarly, the old soap dispenser and faucet in the half bath:

Finally, I also replaced the soap dispenser in the kitchen. That was the most difficult to get to. I accessed it by removing the drawers:

A peek of the old soap bottle:

To install the new one, I reached back through the drawers space and poked the assembled soap bottle and tube up through the hole, before screwing the top on:
