Latest project.
The faucet/sprayer in the septic bay has been dripping and I wanted to fix it.
I did not take pictures as I took it apart, but did as I put it back together.
So if you want to take it apart and fix your just reverse the steps.
this is the faucet knobs and valves taken completely apart.
Everything is plastic and everything can almost be done by hand. The only thing I really needed a wrench for was the fitting that had sealant on and it really should have had any on it.

Note the o-ring is broken here and that was my leak. It is not really an o-ring, but a o-band. Of course no one had it (special part)

I have a selection of o-rings and tried several, I put the whole thing back together to test for leaks several times, I finally ended up putting two o-rings on each valve. The o-ring in the center is the size I used. I had to stretch it over the valve and when two were put together it was almost the same as the o-band that came off.

The valve base is inserted into the valve case.

The plastic retaining nuts are screwed onto the valve bodies and the four notches are lined up with the four notches on the faucet base. You might need a wrench here to get the notches to line up. DO NOT OVER TIGHTEN, if it is tight back off to the first notch, the o-rings are the seal not the tightness.

The plastic pieces next to the base are the nut retainers and slide over the nuts and snap into place.

Here the retainers are snapped over the retaining nuts.

I did put sealant on the treads that had sealant on when I took this apart, but hind sight says it is not needed.

When you assemble the valve bodies into the base make sure the thread are perpendicular to the base. I did not, had to take the whole thing back apart and put it back together correctly.

Now it is time to reassemble everything.

This is the plug that plugs into the back of the tank monitors.

And this is the back of the tank monitor.

These are the hot and cold water lines that connect to the valve bodies, note the rubber gaskets inside the connector, hand tighten only, no tools!, in th background is the black water tank, the line going into it is for flushing the tank.

This is the back side of the panel that holds the faucet, the sprayer, the water pump switch, and the tank monitor.

The check valve is now screwed into the outlet on the valve body. It has in it the same rubber washer pointed out above. That is why there is no need for the sealant on the treads.

Now attached is the hose for the sprayer, it is pictured with the 90 fitting facing down but that does not work, it must face up other wise it hit the black water tank and the panel will not go back in place.

This is the panel turned around so the front is facing out, tank monitor is not plugged in yet and the pipes are not hooked up yet.

The monitor has been snapped into its frame and the wire harness is plugged into the back of it (back side of the panel again).

And now the hardest part of this project. There is not a lot of room here and you want to be very careful not to cross thread the plastic connectors. Hand tighten only. As you can see it was hard to get a good picture.

Another shot, and now is the time to test it (pressurize the system and check for leaks. I let it sit pressurized and went and eat dinner to make sure I had no leaks.

The panel is now screwed back into place and the system is still pressurized, no leaks, no knobs as yet.

One knob screwed on the other waiting it's set screw.

Completed

A job well done if I say so myself.

I guess I will be spending more time doing this kind of stuff as I cannot find someone to do it RIGHT for me.
