Installation of sewage tank

I am installing a full bathroom in my basement. The installation will require a sewage pump and plumbing in the concrete floor. I have already cut the concrete and dug out the soil below to the approximate depths needed.

The question is were can I get detailed info on how to properly install the sewage tank and accompanying plumbing. I would hate to find out I made a mistake after it is in the ground and cemented in.

Also Sewage tanks seem to be sold with and without an alarm. How would you know when a alarmless tank has a malfunction. It seams that it would be a no brainier to get a tank with an alarm
Thanks

sewage tank

thier isnt much info needed to install one of
these tanks.. Just seat it down into the mud
to the right debth. Fill it up with water to to the drain port to
keep it from floating up if their is surface water nearby...

the only thing that is important is getting the drain inlet
deep enough to have fall to the toilet and fixtures...

teh rest is normal plumbing to the fixtures...

I never install a pit all the way in the concrete
usually I leave the lip of the tank above the concrete an inch or
two jsut to keep any basement water from collecting on top of
that sealed lid..... but it works fine either way

just be sure to vent the pit into a good vent somewhere.


as far as an alarm, its not a very important...
I have never instaled one , never worried that much about it.

NOW the PUMP you buy is far more critical than an alarm...


buy a Zoeller or Hydromatic ,
get a pump with a 2 plug wire setup.

one wire goes to the motor and the other wire is the switch
which is independently mounted either to the pump or to the
verticle pipe. The switch plug goes into the wall outlet first,,,
then the motor plugs into the back side of that switch plug...

that way if your switch were to ever fail down the road smoeday,
you can unplug the whole set up and then plug the motor in
directly to the power and pump out that pit full of gooo

you can even get by for a few days by simply plugging
in the moter directly to power and pumpiong out the pit
till help arrives..
( of course it cant be left plugged in or it will eventullly
burn itself out)

then at least you wont have a pit full of sewage to bail out
or pull the pump out of for repairs.......that aint fun.

with a switch that is not intergrated into the motor, you can
usually make repairs without pulling out the pump,

all you got to do is stand on your head and reach
down into the pit and change out that switch..

been there and done that...

pump

Don't worry about the alarm for a basement pump system. You will know when the pump is not working because the toilet won't either. An alarm, and a lot more "bells and whistles" are needed when the pump is servicing the entire house drainage.

Thanks for the input. I have a few more questions

The shower drain will be located between the toilet and the sewage tank. If the tank malfunctions and the toilet stops working is it possible that it could back up into the shower?

Can you fill around the tank and the plumbing with dirt or should you use something else like pea stone?

I have seen in new houses with rough plumbing in the basements that the cement is boxed out. Basically there is a 1' square area around the shower and toilet pipes with no cement just gravel. I was told that this is so you can a little adjustability for you shower and toilet. Is this a good idea? Do you eventually cement in this boxed out area once you determine the exact position of the pipes?

I assume the shower requires a water trap and the toilet does not.

Any and all info is greatly appreciated.

Thanks much
