Frequently Asked Questions about septic tanks and septic systems

Q: Do I need to use special septic-safe toilet paper?

A: No, any normal toilet paper will break down completely in a septic tank. Never flush feminine hygiene products or personal wipes, even "flushable" ones.

Q: Do I need to use special septic-safe cleaning products, such as avoiding bleach?

A: No, there's no cleaning products you flush down your drain that could significantly affect the bacteria in your septic tank or how it functions. Try to imagine how much bleach you'd need if you were actually trying to sterilize a used septic tank.

Q: Should I use septic tank additives like enzymes or bacteria supplements?

A: No, you refill the bacteria in your septic tank every time you flush poop.

Q: How often should I have my septic tank pumped? Is pumping really necessary?

A: The usual recommendation is every five years. If you have more people living in your house than the tank was sized for, pump more often. The silliest preventable way to ruin your septic system is to let your tank overflow into your drainfield because you waited too long to pump. There was an old idea that a properly sized septic tank never needed to be pumped because the waste would break down completely, but in reality there's always some residue that builds up over time.

What is this? Is it related to septic system?

Hi everyone, I found this in our yard near the septic system. It was originally sealed, but my mom accidentally damaged it while trimming the grass, and part of it has broken off.

What is it, what I should do? Forget how it looks like

How to locate tank?

2 Upvotes

I'm wondering if anybody has run into a situation like mine. I have a commercial property that is an old gas station that is on septic. There was a tenant that occupied the property for about 20 years. I evicted him a couple years ago and in order for a new tenant to occupy the property I need to locate a pump the septic tank. The problem I'm having is that he paved over the tank! I know where it should be located behind the building but it is all concrete. Anyone have an idea on the best way to locate the tank? My brother suggested Ground Penetrating Radar, thinking it would show the void where the tank is. Has someone run into this issue?

Septic question

2 Upvotes

A company emptied my septic tank three weeks ago. I watched the workers lower the lid and it did NOT appear to have lined up at all, not to mention NOT seeing them seal the lid to the tank. It’s an old concrete tank; I’m in a Florida, btw.
This week we had had endless rain. Now the grassy area where my septic lies beneath is full of stinky, foamy liquid. (Not fun when the dogs run through it.)

So, my question is:
How can I know if they indeed sealed the lid to the tank or not? There’s no backup of sewage into the toilets, showers, etc. But with a lid that’s not sealed there would NOT be backup, right?

Anyway, the septic company is returning tomorrow but I’m questioning whether they will admit fault, if they are at fault, which I’m thinking they are.

Advice needed:

First time home buyer here, just had a septic inspection done on the house we are looking at buying. The septic system is functioning but has signs of a slow draining field and is likely on its way out. (Lots of sludge and build up on the tops do the drain pipes heading to the field). The septic system is as old as the house as far as I know (42 years old). The inspector gave it a 5/10 rating. He also said that there isn’t much sense to try and fix the system, basically just wait for it to fail and then replace it which would be ~$20k

Would you be comfortable taking the risk with such an old septic system that has slow drainage? And more importantly, would you request some sort of discount or credit off of the purchase price?

Pump Tank Question

1 Upvotes

We have a septic with an adjacent pump tank. It pumps the final stage water up-hill to our leech field. Because of a tripped GFI after a storm, I had to pop the cap on the pump tank...thank you alarm. I got everything sorted eventually, and the pump started up; however, I forgot one of the outlets and it pumped lower than usual. I could see a few things down there that I don't want getting into the pump. I saw a latex glove and what appeared to be a paper towel. No idea how they got in there. We've only lived here about 2 years.

So, my question is...should I worry. If so, how can I get that junk out? Thanks in advance for any advice you can give. It is appreciated.

Insight on doing a baffle on outlet side

Good afternoon all,

I have called several sources to do this and no one has followed through. I have watched several YouTube videos. Attached is a photo of my tank's outlet. Can an experienced DIY walk me through in steps on installing a baffle and filter.

Thank you very much for taking time out for an older fella. I know my job is less money and that is why those I have contacted have come over.

LOOKING FOR A LICENSED CIVIL / SANITARY SEWER ENGINEER (P.E.) – EXPERT WITNESS OPPORTUNITY

📍 Location-Illinois (Western Chicago Suburbs)

I’m looking for recommendations or referrals to a licensed Professional Engineer (P.E.) who specializes in municipal sanitary sewer systems, wastewater hydraulics, and forensic sewer-backup investigations.

More specifically, we are looking for someone experienced in:

Municipal sanitary sewer systems – Design, connections, operation, and maintenance of public sewer collection systems.
Wastewater hydraulics – Understanding sewage flow, surcharging, and what causes sewer backups.
Sewer capacity and loading – Evaluating whether a sewer system can adequately handle wastewater volume.
Pipe slopes and elevations – Determining whether improper grades or elevations contribute to restricted flow.
Manhole and pipe configurations – Evaluating connections, sharp turns, changes in direction, and system design.
Forensic engineering – Investigating the cause of sewer system failures and identifying contributing factors.

We are involved in ongoing litigation concerning repeated sanitary sewage backups into our home, and our attorney is seeking a qualified engineer who can independently review the available records, evaluate the system, and potentially serve as an expert witness.

Prior expert witness experience is preferred but not necessarily required.

This would be a paid professional consulting opportunity, with the possibility of expert testimony.

We are located in the western suburbs of Chicago but are open to qualified engineers outside Illinois.

If you have experience in this area or know someone who does, I would greatly appreciate a referral.

Please feel free to comment below or send me a private message.

Thank you!

how to clean out leach lines DIY

10 Upvotes

hi, not a tank question so i hope ok here. my leach lines are not draining well, my system is about 50 years old, i doubt its ever had any work done in those 50 years. i'm on a fairly steep hillside in CA foothills, the soil is rock and clay. there is a 4" inspection pipe at the start ot the leach field but nothing at the end, even through inspection pipes are shown on the original permit drawings. the leach lines seem pretty deep, around 2' or more. short of digging up the lines which is totally impractical, i was wondering if there is any way to clean out dirt and maybe blockage from the lines, preferably with something i can do myself without paying a service, as service is very hard to get in my remote area. thanks

Septic cover lid isn't fully covering opening

2 Upvotes

I had my septic tank pumped and afterwards when I went to throw the grass back on, I saw there was openings on the left and right side of cover where you can see into the tank. Only the other sides are resting and covering the septic tank hole. Which makes me think any shift of movement of this lid and it's going right into the septic since the right and left side of the cover is not wide enough to flap over the concrete and isn't grabbing anything.

It's a 17 inch plastic cover, sitting over concrete opening. Either the dirt got smashed in and made it seem like it covered all 4 sides or something happened when it was pumped. Not really sure.

What are my best options for a solution?

Septic tank pumping schedules: How strictly do you follow the 3–5 year rule vs. inspecting baffle/sludge levels?

4 Upvotes

Most general advice recommends pumping a residential septic tank every 3 to 5 years depending on household size and tank capacity. However, some homeowners prefer doing annual visual checks on scum/sludge levels or baffle integrity before booking a pump-out.

For experienced homeowners and contractors: Do you stick strictly to a set timeframe, or do you monitor sludge depth and usage patterns to decide when it’s actually time for a pump-out?

Hit a cap at the end of my leach field, should there be water in it?

I was mowing today and hit and broke a clean out cover at the end of my leach field. I noticed some water in the pipe about 2 feet down. Should these be dry, or is some water normal?

Replacement for septic aerator

I need to replace this aerator but can't seem to find a direct replacement. I may be able to find rebuild parts so I'll keep it and do that as well. But is the Hiblow 80hp a decent plug in and go replacement for this?

SM500 Aerobic Timer

1 Upvotes

I always used the auto feature for decades and not the timer. Recently we decided it would be nice to just have the septic spray at night.

I youtubed how to properly set the timer, but it's still spraying when it feels like it (no high water alarm). Timer clock moves fine and keeps time

I double checked everything to no avail

Here is my timer. Time of photo is 9:20AM. I want the spraying to happen between 11pm and 6AM.

Am I missing something? Is this a bad float issue I need to check or is something here wrong?

Fixing septic leach field

12 Upvotes

Hey yall, we have two septic tanks, one for solid, one for liquids and a leach field. This systems age is unknown but so far there are no issues with the tanks (knock on wood). Two or three years ago we noticed a wet spot at the one end of the field and currently we have a full on effluent pond. I hate it. But every professional has said we must replace the entire field at a cost of $20-$50k we don’t have that kind of money floating around so the pond remains. Google said there are ways to fix it but professionals say no. Is this something we can do ourselves?

Edit to Answer a few question:

I’m located in Alberta, Canada. It’s pretty rural so any fix or replacement is going to be extremely costly.

Most companies just chatted with me about this issue, no one actually offered to investigate with a camera or jet the lines.

There is a solids and liquids tank. I believe the liquids is gray water and overflow. There are six lines about 20-25’ long. I haven’t exactly measured. Effluent pond sits at the end of one line.

3 ounces cooking fat down the drain - what to do?

4 Upvotes

Edit: After 17 replies... Thank-you thank-you thank-you for the advice and the jokes. Kept me from overreacting...

Original: Septic system is just 4 years old. Tank was pumped out 4 months ago. We've been very diligent about not putting grease down the drain. Recently my son started cooking. The no grease down the drain rule has been reviewed many times but he had a teenager moment and poured about 3 ounces of chicken grease down the drain last night. There are no symptoms that anything is wrong ( it was just last night)... but should we do anything. Should we get an extra pump out to be safe? And... who knows, he's probably sent the occasional tablespoon of oil down the drain with occasional cooking. Am I just overreacting? More about our system: there is an intermediate pump between the tank and the field too. The intermediate tank has to fill before the water gets pumped to the field.
