I am moving into a house on Friday with a septic system.

The sellers recently had it pumped and serviced, I just have zero experience with septic systems.

Are there any tips, tricks, things to keep an eye on?

Get a copy of the service report from the seller or have your own inspection done just to be sure it's in good shape. Does it have an alarm on it? They're pretty simple systems. Don't flush anything except TP and have it pumped every 3-5 years depending on household size. Also, if you have a drain field, don't run over it. Ask me how I know

Just make sure your aerator pump is working. You know if your system has a submersible pump in it?

Make sure you pump it every 3-5 years because it will back up into your home. My parents found that out this weekend

We had a septic tank at our first house. Just a few quick thoughts.

1) You need to be aware of the location of the tank and field lines if possible. Don't put something on the tank permanently. You want access to it in the future.

2) don't drive over the field lines with anything heavy, my lines were made of terracotta clay.

3) use Rid-X or something similar every so often.

4) don't flush anything other than TP.

5) don't use a garbage disposal in your kitchen sink. It all goes to the septic tank. They increase the solids in the tank and will shorten the time between pumps. A least that's what our septic tank cleaning company told me.

Get a reputable company and have it inspected have them do everything that’s been mentioned if it’s not in good shape you can start burning through cash quickly

Thank you for the replies. The sellers had it inspected also , I will get a copy of the inspection report from my realtor.

It looks like field line location is super important. I will try to find that out.

On the Rid-X, is this something added to the tank every once in a while?

Wife grew up with a septic, she just remembers her dad being super strict on not flushing tampons

ETA: I do not know if it has a submersible pump, but will find out and report back.

Yeah, just pour it in one of your toilets and flush. It supposedly keeps the bacteria in the tank at a healthy level so the solids break down and fall to the bottom of the tank. The fluids will leach out into your yard via field lines.

Contact a local company to figure out exactly what you have. A treatment plant is maintained and operated differently than an older septic system.

As far getting the sept tank pumped out.... With just 2 adults and putting very little in the disposal you should get 8+ years. 2 adults and 2 children, 4 to 6 years.

Something not talked about is don't dump cleaning chemicals down the drain. This can kill the bacteria in the sept tank.

To check the air pump..... There should be a short section or rubber hose next to the air pump. Disconnect the hose and see if air is blowing. Also, there is an air filter on the air pump. This filter should be cleaned every year or two using a water hose and maybe scrubbed with some soap if it is very dirty. Dry it off before reinstalling it.

If your city does home compliance checks. A sept tank must be pumped out if it is over 50 % full of solids. This cost about $500-700.

Older systems will gravity feed out to your field lines Newer systems have a submerged pump that feeds your discharge line. Some systems it feeds sprinkler heads. So long as your aerator pump is rolling your tank the system should be self sufficient. Like others mentioned, you may need to get it pumped out every 5 to 10 years.

Main thing I’ll add: In all likelihood, every drop of water that goes down your drain will enter your drain field. Depending on your soil, this may necessitate water management during times of heavy rain, otherwise you will overload your drainage field.

My soil is rocky clay so we manage water usage during super wet times.

Some folks have a grey water system; that’s different

For those that have sprinkler heads, does the spray area stay too wet? I’m asking because I will have one in the new house, and I’ll also have a sprinkler system.

Would I be better off having irrigation in the entire yard and have the septic sprinkler spray into my 20’ of buffer zone (pine trees and brush I’m leaving to separate my lot from the one behind me), or would you use the septic sprinklers in the rear of the usable yard and not have the irrigation sprinklers hit that area?

If you have an external aerator (air pump) in addition to cleaning the filter like another poster mentioned you should also change the internal rubber diaphragms in them every 2 years or so. I just had to replace mine due to neglect. $230 bucks. They will dry rot and crack. You can google the pump type /serial number and buy a service kit. There are YouTube videos on how to service them. It’s not that difficult.

ZEP makes a product the same as Rid-X for a few nickles less.

I don't notice water pooling or ground saturation. If it's been raining a lot, everything is comparably wet for the most part. If it's dry, it evaporates pretty quick. The grass around your sprayers stays greener for sure. And it is good for watering bushes and trees.

Locally, they don't allow leach fields anymore, and I would say leach fields are less optimal than aerobic systems (sprayers). Leach fields require the soil to be well draining. If the leach fields are get saturated from rain, it won't drain the lines meaning the water backs up into the house. Sprayers spray that shite water regardless if it's saturated or not.

My only experience is the house I'm in now. We've been here 8 years now. Never had to pump the septic system, and have only had to replace the aerator pump. We use our garbage disposal, and the dishwasher and washing machine drain into it.

If you're building a house and don't have to worry about code per se, drain the dishwasher and washing machine straight to the ground. Otherwise, it probably wouldn't hurt anything.
