How to connect new DIP to existing RCP? 2

[pipe78]

Connect new 36" Ductile Iron Pipe to existing 36" Reinforce Concrete Pipe. How can I do? Can I use Steel Couplings Reducing? Thanks.

Why not use a concrete junction box.

I doubt they make a Fernco Coupling that big, but they might be able to help. Cheap, reliable, easy to install. That is a specific brand, I*'m sure there are other similar products. Check here:

But semo's idea is way better, if you have budget (and inlet would be less than $1000 if it is less than 8 feet deep). A junction will give you access. A junction might be required by local ordinance, so check before you spec a Fernco coupling.

If the junction box is unnecessary, the typical way is to use a reinforced concrete collar.

semo: Thank you. I can't use concrete junction box, because budget.

lha(Steve): You are right. That's why I am thinking about Steel Coupling Reducing:

By the way, why do you give a "Remember"? You know Chinese?

cvg: Thanks a lot. I don't know if the reinforced concrete collar can be used for DIP?

 

[cvg]

yes, typically used to connect storm drain pipes of different sizes or types or at a change in alignment or grade. Standard details may be found on the MAG website at:

I don't know Chinese. The quote is from a thesis I've recently read:

"The Death of Environmentalism, Global Warming Politics in a
Post-Environmental World" By Michael Shellenberger and Ted Nordhaus. Very good reading.

CVG: Thank you very much about the technical resource. I'll use this in other projects, because it is combined sewer pipe this time.

lha(Steve): Thanks for your response. I am insteresting this word because I know Chinese.
