Very Important Cesspool Safety Warnings
Question: When is the best time to install a new cesspool?
I need a lot of information because I am going to buy a new cesspool. When is the best time to buy one? I was told winter is the best time to buy a new cesspool? But the ground is frozen now. What temp is right? What is the average price? House was built 1950 (maybe). Does new cesspool come with new cover? Can I have my clothes line on top of old cesspool? How do I get rid of odor in my basement? When they put the new cesspool in do they check pipelines in and out of house? If so how? Do I need to get new pipes in side? Does a plumper know best, when to replace pipes? - S.H.
Reply: Wet warm weather
The season in which a cesspool is to be installed affects the cost and may affect the outcome too:
So it's probably cheaper and smarter to dig during the un-frozen wet season.
Of course, if your building relies on a cesspool or drywell to function and the present system has failed, you may be forced to install the new cesspool or drywell without waiting.
Cesspools, if you buy a pre-fab pre-cast unit, are made of concrete. You may have a choice of cover - a heavier duty one that can be driven-over without collapsing is smart. But a safe cover must be included in your bid price regardless.
Watch out: falling into a cesspool or drywell is likely to be fatal. See SEPTIC & CESSPOOL SAFETY
Putting a Clothes Line over a Cesspool:
A clothes line won't hurt the cesspool if you don't drive a post into the cesspool top.
Getting rid of Old Sewage Backup Odors:
Odors go away by cleaning and sanitizing the area of any sewage backup and airing it out. If odors remain you may have an outdoor failure and outdoor sewage odors as a source, or you might have an indoor plumbing vent problem.
See ODORS & SMELLS DIAGNOSIS & CURE for details.
Building Codes, Permits, Approvals for Cesspools and Drywells
You need an experienced plumber and cesspool. installer to help locate the new cesspool, connect existing building drains to it, and to assure that the building drain/waste/vent piping are working properly.
Don't forget to obtain a building department or health department permit and approval, and to install it correctly and safely.
Watch out: Some municipalities do not allow cesspools - so check with your building department. .
