anyone have a 1.5" grey water discharge?

due to space constraints we installed a 1.5" greywater discharge pipe.
i have a few options;

convert the 1.5" to 3" with an adapter and use the same hose as black tank :



or use a 1.5" fitting designed for a macerator system...with a drain adapter and 4 in 1 elbow adapter...



right now its just a 1.5" PVC pipe... any other suggestions or thoughts? thanks!!

Time for some valuable thread resurrection...

I have the same issue with my rebuild. Using 1.5" pipe for my graywater tanks to maintain clearance and minimize clutter. Have it piping up to a 1.5" valve, with a slip hub ready to go. What do I do from there?

It seems like there are two issues:
1) I need to somehow get graywater out of my trailer without rigid 1.5" abs pipe the whole way. 1.5" hose doesn't seem to exist for rvs unless I'm blind.
2) I need to get that graywater (sinkwater) to a hookup at a campsite. Seems like one of those all-in-one adapters would do the trick. But do I really need to lug around a 3" drain hose and fittings and all just for some potential 22 gallons of sinkwater?

And yes, I've used the search tool.

Almost a week, no replies?

Bump for some help.... I'm installing the tanks this weekend and would love to assemble the whole system.

You are correct that the RV-type hose and bayonet fittings only comes in 3" diameter.

The way I see it, you have four choices.

1) You can T the greywater and black tank dump valve outlets s together and have the wastewater from both of them drain through a single 3" bayonet fitting so you can use the standard hoses. This is what Airstream and most other makers are doing on new RVs -- it's rare to see a greywater tank plumbed with a 3" drain. That won't work unless the drains are close together though.

2) You can adapt to a 3" bayonet and just use the regular hose. You're going to need it for the black tank, anyway. Either use the offset adapter in the photos upthread or a plain adapter, depending on what fits the best.

3) You can build a custom 1.5" drain system. You would probably want to use cam-lock fittings, which are widely available in all sizes both plastic an aluminum. They aren't expensive. (Here's one source: Aluminum Camlock Fittings, Polypro Camlock Fittings). There are a variety of choices for hoses.

4) You can use a garden hose. The main problem with doing so is that if you are at a dump station it may take longer than you would like to empty the tank. You will also probably have occasional problems with clogging. Like many people, I adapt down from 3" bayonet to garden hose for greywater when in a site with full hookups, in many cases, because the collapsible 3" hoses don't hold up well.

I'd opt for choice 1 or 2.

This is how I did mine. After dumping black tank I switch to grey with same hose. Made adapter to go between 1 1/2" valve and hose adapter.
