based on New York State Septic System Regulations

Model septic system design specifications & regulations:

This article series uses the New York State wastewater treatment standard for individual household septic systems (Appendix 75-A) to provide an example of state regulated design and installation of both conventional tank and leach field septic systems and alternative septic system designs, including raised septic systems, septic mound systems, intermittent sand filter septic systems, and evaportion-transpiration septic systems.

Is there a code for VENTING the plumbing in homes

Is there a code for VENTING the plumbing in homes so NO SEPTIC GASES seep or vent into the home.

The home I'm in does NOT have any venting to outside for the plumbing, & the owner put the old school vent cap in the basement, after we smelled sewer gases in the home LAST winter not as strong. But everytime something drains we smelled the gases.

Now it's winter time & the sepric gases are CONSTANT h strong whereas everyone in our home no matter how much I air the house out we all have constant uppwr respiratory infections, & our children NEVER needed any antibiotics ever the youngest of 4 now 14 never ill & now we are always congested with sinus problems.

My Husband wirh 2 Leukemia's developed double pneumonia landed in the Hospital & in septh testing revealed bacteria from such type of gases ruling out everything else that could cause it.

There's a discrepancy because the older generation DOESN'T believe there's any laws or codes that require SPECIFIC VENTING of pumbing to outside & the basement ONLY venting is NO LONGER legal as a result of such health issues as this.

Can someone PLEASE guide me to ANY written laes about VENTING plumbing for septic gas in homes? On 2018-02-11 by Dees

Depending on where you live local plumbing regulations or building codes perhaps modeled after the uniform Mechanical Code specify quite clearly the requirements for proper venting of the building drain system. If your building has no venting installed it is potentially unsafe as well as prone to clogs and blockages.
