septic tank question

[goeduck]

It's not that a garbage disposal is really that much worse, it's that it's just more stuff to deal with. Poop & garbage disposal grindings all get broken down. They all getting converted into lesser volumes of sludge that cant be digested or broken down further. The best way to prevent a septic tank from filling with sludge is minimize the solids you put into it.

We put vegetable scraps into the compost for use in the flower beds and garden. Why waste it in the septic system? One of the troubles with garbage disposal grindings going in the septic tank is that some of it floats adding to the scum layer. Too much of a scum layer can allow scum to go out the baffles to the leach field plugging it up. Not good. Also, people put meat scraps through the garbage disposal which contains fat. Not good at all for a septic tank or leach field, it also plugs it up.

people refuse to understand the septic tank system and use it like city systems. Limit input to toilet paper mild detergents not much bleach and other than roots which can be controlled with copper sulphate put into distribution system every 6 months, the system last forever.

yes i thought about that but after thinking about it for a while figured it was a crappy idea

No, previous post was right. Two 45s with a short section between, clean outs every 50 feet. Reason being, most snakes only reach 50 feet and most snakes hate 90s. Make sure there is a tee at the tank outlet too, makes it harder for solids to float into the drain field.

Not questioning you, but can you show me a picture of what you mean, so I can understand this idea?

If we are talking about the t on the outlet, yes. Great picture. Stuff will 吐loat in/on the scum layer and the longer tail on the t is to keep liquid only in the drainfields (absorption field). Once solids start entering the field, it becomes a big issue. Next thing you know, the tank is overflowing and someone called and complained. It may very well be salvageable but (at least locally) the inspectors know zip about it so they condemn and order all new.

The advent of home inspection prior to sale is not a great thing as more and more inspectors enter the market. Some of these inspectors are claiming they performed a septic system hydraulic load test and the system failed. Ok , what does that mean.
You introduce a specified amount of water and see how long it takes to leave the tank. Sounds great, what痴 the specified amount? Well, depends who you ask. What痴 the time for it to evacuate, depends on who you ask. A qualification training seminar was given for my area. Only one company within 125 miles of us attended the training, guess how many are charging for the test.
After a home inspector failed a system and the state concurred, we found a collapsed pipe between the outlet and D box. 1500 dollar repair instead of 8000, the seller was a happy camper.

There are baffles at the top & bottom of the tank between the inlet & outlet pipes. That should prevent scum & sludge from migrating from the inlet side to the outlet side. Unless of course you dont pump the tank occasionally then the sludge eventually makes it's way over the baffles & into the outlet pipe then plugging the leach field.

Found a decent diagram. Not fundamentally different than the first, but a bit more complex.

Depends on whether you are the seller or buyer. My church had a piece of income property with 2 rental houses on. They bought it back before inspections were mandatory and no one checked all the paper work before the sale as they say only the cheap price. Reeling forward, the reason it was bought went away and the mortgage/taxes/insurance was a cash drain so put it up for sale. I was interested in buying it till I checked the back records. Property record showed only one house and one septic tank. One house was bootlegged in (relocated) and tapped to the existing tank. I knew I would not get a mortgage w/o upgrading the property into compliance which negated the sale for me. I provided the info to the church council and warned them about the cost. I made a full price offer that included seller would bring the property into compliance. They turned it down, could not afford the upgrade ($40K). 2 years on the market and finally they sucked in a cash as-is offer at a low ball price that almost paid off the mortgage.

PS- I am good at going off track also.

We inherited our land with a conventional system that was installed sometime in the 80's. We had to doze the house and turned an existing Morgan building into a cabin, where it was located necessitated a 90 degree turn for the septic line. My FIL used 3" pipe so we also had smaller pipe to deal with. I used a long sweep 90 5 years ago and we e had zero problems with it. We've been here full time for 3 years now. I did slope my runs 1/4" per foot also. The toilet actually has to traverse four 90 degree turns to get to the tank, they're all long sweeps.
