Will discharge hose get clogged?

Do you think my discharge hose from my head will get clogged if I put a 90 degree elbow fitting in? (super tight bend needed to get to holding tank)

I think it's courting a clog. If there's absolutely no other way, then carry a toilet snake onboard with you to chop up and remove clogs.

Count on it...unless it is a "street L" that slopes correctly, but I think those only come 1.5" and up...

Perhaps you could loop a coil in the hose in order to make the turn? Longer hose, but it'd be a smooth, circular path.

I think as long as its smooth inside you may be OK. As long as your guests don't try and flush the wrong things.

Many heads have a 90 elbow off the back of them. Most heads can pump up to six feet. Depends on how far away your holding tank is, since 90 elbows create more friction than straight pipe.

Thanks for the input everyone. I haven't been able to find any gradual curved fittings that would work on the 1.5" hose. I think a big loop might be the way to go.

I guess another option might be to step up your hose size in the middle, where the 90 degree elbow would be. If you could find some adapters to step up from 1.5" to 2.5" so that traffic flowing through the 90 degree elbow would meet less resistance, then you might be safe. Then, you use adapters to step back down to 1.5" to enter your holding tank.

Or if possible, adapt your holding tank hose nipple to 2.5" and just run the larger size as much as you can.

Dometic sells a 90 degree kit. No idea what it is. But I'm guessing with thier super-stiff odr-safe hose it's sometimes needed.

I just talked to Dometic anbout this. Nope, adding PVC is no problem. The kit is a dwv fitting with 2 smooth addapters glued in.

Go for it.
