Pictures are worth a thousand words (ha ha), but maybe a few additional words will help.
2nd picture shows how I covered the hole and got the floor level. I cut a 3/8th in thick piece of plywood which I painted to seal it, the size of the base of the Nature's Head. I then cut a hole in it just large enough to go around the flange or raised area. I then cut 2 pieces of rubber which you could use something like from a old car inner tube, just so it's flexible. This I butted together centered over the hole, this provides a way to reach into the hole to be able to hold the nuts which are used to fasten the board down. When drilling the 4 holes through the board and fiberglass floor be sure to position them so if you decide to put the original toilet back in it's base will cover the holes. I used stainless steel bolts with counter sunk flat heads and ss nylon lock nuts. After tightening the board down you can use some type of rubberized tape to seal the hole.
When mounting the Nature's Head mounting brackets proceed as normal making sure to position them inward so they are screwed to the board only, not into the fiberglass (short fat screws.
The vent when cut to accept the "T" pipe will flex enough to accept the "T" if cut a little larger than what would be normal. The "T" can be slid up or down a little each way to position it parallel with the toilet's vent. No need to glue it, it's not going anywhere once hooked up. You can see I used a rubber boot from a flexible pipe coupling.
Have to leave now, but am posting this with more to come.
Nature's Head install cont.
Pictures 4 & 5 show the black washing machine hose I used to connect to the urine drain on the toilet. I first drilled a hole at a slight downward angle in the vent pipe that was a little bit smaller than the threads on the brass male pipe thread to male hose thread fitting. Just using hand force without threading the vent the brass fitting screwed right in.
on the toilets outlet I hand screwed on a 1 inch female to female pipe thread pvc fitting, again without threading. In both cases the fittings created their own threads. On the toilet pvc fitting I added a plastic fitting with male pipe threads and male hose threads to go into the pvc fitting. On the hose threaded end I connected the two parts of a hose quick disconnect (brass or plastic will work) this comes in very handy when I empty the toilet which I take outside to do. The black appliance hose I used is a little long, but I wanted the loop to help prevent any smell coming from the black tank.
Lastly you can see the 1/2 inch board in front of the toilet which is fastened to the board covering the original toilet hole with 2 small screws and has a spacer board for support on the front edge.
Understand you will not be able to put your feet on the floor when sitting on the toilet (thus the board in front of the toilet) and men and boys must sit for both #1 and #2 on a Nature's Head.
Only one problem encountered so far and totally my fault, when putting the cocoa coir in one time I accidentally spilled some into the urine holes causing the hose to plug up which then caused the you know what to back up into the composting tank which ended up requiring a very soggy sloppy clean out job. Learned a lesson the hard way, cover urine holes or be very careful when adding coir.
We're happy with the Nature's Head, we've used it for 2 years in our previous Jayco TT and now 1 year in our Casita
. It takes getting used to, but we feel the benefits, less fresh water usage, less chance of filling the black water tank when boondocking
, no toilet flushing pump noise during nightly visits outweigh any negatives, toilet paper for women urinating should be disposed of in a separate container which we have next to the toilet.
Don't worry about smell, with the fan there is none.
That reminds me connecting the fan to the bathroom light
will work, but what I did was run the fan wire thru the wall where the pipe for the original toilet pipe goes thru. this comes out under the kitchen cabinet where you can connect it to a couple of 12 volt wires.
Alright, that's it. If something is not clear ask away. Good luck.
