Backwater Pit?

neolitic

Plumber says he's open for better ideas,
so I come to some of the finest minds
in the business for a new one.
The rest of you are welcome too.
Need a backwater valve/sewer check valve
to keep back-up out of basement in these
50 year rains that now come every year.
Can't put it in the basement.
Line exits directly under a 4 step stoop.
Only location left is under a patio that is
going to be replaced this summer.
Okay, plumber says he needs like a 3'Ø
pit so that the valve can be replaced
in future, and to accommodate the
down stream cleanout.
The line at this point is @ 6' below grade.
Best that I can come up with is a
precast manhole section and bell.
Maybe a piece of corrugated culvert
pipe, but that leaves me laying a cmu
brick beehive to reduce for the lid?
Anyone know of some new product
lighter, cheaper than precast concrete?
How about castings ligher duty than
a standard manhole cover?

Thanks for reading my little novel.

Concrete is your best bet. Check with the local utilities supply house and see if they stock grease basin covers, the are smaller and lighter than a manhole, but are somewhat limited in availability.

Thanks.
Sounds better, just hoping for something
along the lines of the heavy cast plastic(?)
covers they put on irrigation pits.
Thinking that since they make septic
tanks and dry wells out of plastic
maybe there were other options there.
Just about tired of Googling for now,
and my plumber is "anti-internet."

I've always used concrete for any type of pit but I know someone must use fiberglass or plastic pits.I would have to search just like you Neo. The deeper the line the bigger the pit,that's the problem.I wouldn't mind seeing what you found 3 Kings,the back-water valves have become code here as well so it's a matter of time before I come up against the same thing in low areas.

I hope he will post on here too.
Figured this might not be a one off
and some of you guys might appreciate
the info as well.
Frankly I thought it would be something
that I (and my plumber) were just to
old fashioned to know about the hip new
solutions.
Believe me I've been through a bunch of
web sites looking but haven't found the
secret hand shake just yet.

On supplier I deal with told me to use a 36" PVC pipe with reducing cap 36x24 then the a sewer rim with lid (like water meter pit lid) I believe with 10' of 3" PVC and all the reducing caps and lids, with the back flow device it was around $753.00 for material. Call Fergusion Water Works. If you need the number I can give it to you.

I just had Tim over there look this up for me. I ws wanting to do concrete but the cost is un real! And for asmuch traffic this area will get didn't need concrete.

Threaderman

Just try to find a supplier that deal with water and sewer main pipe. That's how I found what I was looking for.

I hope this was helpful.

Thanks!
Been looking at 36" corrugated, but never
found a decent reducer to go-with.
Now I'll have to see if Dick thinks he can
squeeze an old plumbers butt through
that 24" lid.

BTW, you'll never have to worry
about me scabbing sewer work!
That's about 10 points after the
last thing on my to-do list.

Hey Neo,

My excavator/plumber has done a job just like this down in Greenwood.

The El Dorado subdivision is pretty well known for sewer back-ups in heavy rains. I know he used a 4' black corrugated liner for access. I'll call him tomorrow & ask how he reduced it.

I'm think I might of confused you a little. They have an extension ring that is 20x36 which the lid sits on. You just got to dig down to the rim of the 3" pipe to remove the full cap! (whole thing cover and cap) Than that Plumbers rear will fit with no problems. IF chris can find out what he know that would be very roomie to work in!

Aaah, no good.
There will be a concrete patio over this,
no "digging down" for access.
Now I see what you meant.
I'll bet someone makes a
2X2 access cover and transition
for things like this out of plastic
or some such.
Hope Chris' guy has a trick up
his sleeve.

Sorry it took so long.

The previous project, he used 4' corrugated to line the pit, with a man-hole reducer on top.

He did say, however, that he's heard they now make a 6" sleeved access for these backwater valves, that come with a way to remove the plug to allow obstructions, etc. to pass.

He wasn't sure who made it, but saw it in plumbing class recently (he's going to night school to get his master PL.)

Thanks for taking the time.
We talked about the sleeve deal,
but my guy won't do it unless there
is access to change out the
whole valve.
I like that kind of thinking.
Gonna keep looking for some light weight
reducers and lids.
Just can't believe they aren't out there.

If I read your post right your plumber is not license correctly or not at all for the state of Indiana? (State of Indiana doesn't have Masters any more it's called a Plumber Contractor License). I would start to look for a proper License Plumber before he/you get caught and fined!
As for the Backwater Valves you mention Indy Winnelson carries them.

Neo.
Try to contact Ferguson water works.(317)546-2013 I usually deal with Tim Evans. He Could help point you in the right direction.
