Sewer Back Up – Modified Overhead Sewer

sewer back upWhen rain overwhelms a sewer system and sewage is backing up through basement floor drains, bubbling up basement toilets or shower drains a Sewer Backup Prevention System can solve the problem. Water Bubbling from Manhole or Sewer Grate is a good indication that a municipal sewer system is overwhelmed and cannot handle the capacity. Older homes are designed with gravity systems are most vulnerable to sewer back up. The illustration to the left shows the typically sanitary design in older homes that are susceptible to Sewer Backup when heavy rains overwhelm the city’s storm sewer.

All plumbing fixtures in the home end up traveling through the system always heading downhill utilizing gravity eventually emptying into the city sanitary system. 99% of these older homes are not equipped with a Sewer Backup Prevention system..  The picture of the manhole cover being lifted by water shows an overwhelmed system. All the sewer lines are well below grade and when too much sewage overwhelms the system, waste water comes up from floor drains, shower drains, toilets, slop sinks etc.  The system shown in the illustration is the “MOST LIKELY TO FLOOD” due to Sewer Backup.

Concrete Cralwpsaces Corp. Modified Overhead Sewer System

Modified Over Head SewerSewer Backup Prevention can be accomplished in a variety of ways. The best way first. The Modified Overhead Sewer or Overhead Sewer is engineered to be the least likely to flood due to Sewer Backup. All newly constructed homes come with a built in design that makes it virtually impossible for basement flooding or crawl space to have Sewer Backup because all plumbing fixtures do not send the sewage or waste to sub basement floor sewer lines. All plumbing fixture, shower drains, floor drains, toilets, slop sinks, washer machines are connected to and ejector pit which pumps the waste    overhead directly into the soil pipe or 4” stack that goes directly into the city sewer system.  The illustration to the left give you usual example on how it works and shows how it is so effective in preventing Sewer Backup and Basement Flooding. Sub Floor sewer lines are not connected directly to the city sewer. When the sub basement floor sewer lines are not there, sewer backup and Basement Flooding is eliminated because the possible ways sewage can enter do not exist.  The ejector pit has a check valve which prevents sewage from flowing back into the pit. 

Sewer Back Up Issues in The Chicago Land Area

Some cities, like Chicago have a system this combination Storm and Sanitary.  Other Cities have two systems.  One is for Sanitary the other is for storm water. Although is much worse to have a Combination Storm and Sanitary Sewer System because Sewer Backup can allow some of that nastiest contaminants known to man into the living space of your home.  This must be addressed at all costs. There are other reason why the Modified Overhead Sewer is the choice option of many of our customers. Mechanical flappers are not used in the Modified Overhead Sewer Backup Prevention System. Any object that can block the flapper (back flow valve) from operating and causes the Flapper to not close; tree roots, forks, knives, toys, sun glasses, diapers, ad infinitum.  Yes, these are items that we have found in some of the most expensive (the vault in the front yard) Sewer Back Flow Systems that fail because of the inherent flaws in the design that will cause another Sewer Backup. You must be asking, how can my older, sub floor sanitary system be converted into a modified overhead sewer which will virtually eliminate Sewer Backup and thus Basement Flooding and Crawl Space Flooding. First of all you will want to hire a Licensed Plumbing  contractor, like Safe Seal, who understands the problem and understands how the fix the problem. Locating the sub-floor sewer lines and abandoning the redirecting new sewer lines to the ejector pit. The bottom line, some mods are more complicated than others and cannot be fixed without the know how.  Cameras and sewer line locators are used to identify exact location of the sewer lines and to visually inspect the lines to make sure that are in working order. All basement slab penetrations, floor drain, bath tub drains, showers drains, laundry will be disconnected from the main sewer line and then routed to the new ejector pit which will discharge to the existing 4” stack.  All abandoned sewer runs will be capped and sealed per plumbing code. Any cement that was removed to accommodate the new system will be replaced. You now will have a Sewer Backup System that is engineered to be the least likely to flood your basement with raw, nasty sewage.
