Drainage box below basement shower

I have a 1938 house with a basement shower. Below the drain is a metal box that the water drains into. When it reaches a certain level it drains into the outgoing pipe. We are trying to fix up our house to sell and this has been a major problem. there isn't a swan pipe on the drain and we occasionally smell sewer gas. How can we fix this w/out breaking the bank?

Re: Drainage box below basement shower

You probably do not have a proper trap, that is why you smell sewer gases. Code requires a trap. When you say you don't want to break the piggy bank, I understand, but renting a jack hammer to install a proper trap is not that expensive, if you're willing to do it yourself. If not, then it would be expensive to have a plumber do it. Why not break it out yourself, and if yo feel uncomfortable with the plumbing, have the plumber do what he does best. Depending on the elevation of the drain pipe, you may have to install a false floor under the shower to obtain proper slope.
