Taking my time, making sure the holes were placed correctly, and a quick lesson in learning to use fiberglass is what it took for me and everything came out perfectly.
I'm happy to hear that the PVC pipe connectors are tapered because that makes the difficulty I had connecting them make much more sense.
As for the composting toilet, I think your Airstream is certainly worthy of having a proper toilet. It might be a bit of a challenge but it's certainly worth it.
Boy, does that sound intimidating. I am comfortable with doing electricity but plumbing is scary. Now, I have some questions: 1. Did your tank come with the holes already cut and all the fittings already installed? 2. Is your tank a curved one to fit in the corner or did you use a rectangular one and fit it as close in the corner as possible? 3. Is your tank sitting on top of the floor as opposed to under the floor? 4. Do you use just standard PVC connectors like you'd use in a real house? 5. Does the dump valve (the black thing with the handle) just fit right on the PVC?
I think the tanks I was going to order are made of polyethylene resin. Should I go with a fiberglass one instead? I am ordering 3 tanks - fresh, gray and black. I was going to order from Tank Depot but if that isn't the right kind of tank (Ronco 23 Gallon Marine Water Tank (RW-B450)
) to get then I'll keep looking. Inland has a curved on-the-floor black tank but I think it is too big for my space. Andy said it was something like 27" x 27" x 61/2" and the space I have is just about 19 or 20" from the side of the trailer to the little bathroom wall. Maybe I could extend the tank out into cabinet space... My little bathroom is tiny - no shower, no sink, only a potty. A porta-potty would be easiest and cheapest but... YUCK!
Tank Depot will put in whatever holes and fittings I need. I'm ok figuring out the gray and fresh tank fittings but when it comes to the black tank, I stay up at night worrying about it.
The reason I was considering a composting toilet is because another 'streamer has one in her trailer and loves it. But it is pricey - $850 + shipping. That's awfully expensive poo.
Thanks for any more help you can give.
