ABS pipe vs Heat?

[evy]

Hi everyone,

I'm working on my very first DIY camper conversion, using a 2010 extended Ford E250.



I will start installing ABS sewer pipes here and there very soon, I was under the van yesterday and I found a great spot to run a pipe but I wasn't sure if the heat would be a problem, if you look at my plan, I have pipe from the shower to the kitchen sink location (from the driver's side to the passenger's side of the van)

the pipe would be above and cross the gas tank, drive axle, exhaust muffler, and it would be centered right over that cross member, sloped toward the sink (see picture)



In this picture you can see the muffler's heat shield.



So my question is, would the heat be a problem for my ABS sewer pipe?
The pipe would be protected by the muffler's heat shield and that cross member would also act as a heat shield, but is that enough?


Thank you!

ABS pipe was used for quite a while as high efficiency furnace exhaust. I doubt you'll ever melt it if kept away from the hot engine exhaust.

I'm pretty sure that abs is used on motorhomes, seems reasonable.
