Not our usual type of post.... but we have to give a big shout out to our friends over at Allied Septic & Drain for dropping off a brand new portable toilet this morning. Behind every portable toilet is a person who manages it. For us, that person is Dave. Every week he comes (often with his adorable son in tow) to clean out the toilet and keep it fresh for all of our amazing customers. Thank you Dave and Allied Septic & Drain for all your hard work and being one of the many facets in what keeps the Brick House going. We appreicate you guys!

🚨 SEPTIC MYTH SPECIAL EDITION 🚨

“My septic tank only needs one cover opened to be pumped.”

❌ Not always true.

We responded to an emergency backup call today where the customer’s septic system had been replaced about 5 years ago with a two-chamber septic tank equipped with an outlet filter.

The customer mentioned the tank had been pumped roughly a year ago… but something still wasn’t adding up. 🤔

After locating and opening ALL the tank covers, we found:
💩 The main chamber was completely full to the brim
💧 The outlet side looked more like what we’d expect from a tank pumped a year ago

The issue?
Only the outlet chamber had been pumped previously, while the main chamber — where the solids actually collect — was left full.

That’s a little like vacuuming only one side of your living room and wondering why the house still looks messy. 😅

To make matters worse, the inlet became plugged due to the backup. After some elbow grease, a hydro jetter, and a freshly cleaned septic filter, we had the customer back up and running properly again. 👊

✅ Septic systems are NOT all built the same
✅ Some tanks have multiple chambers
✅ Some have filters that require cleaning
✅ Proper access and documentation matters

This is why it’s important to use a company that:
📸 documents service properly
📝 understands modern septic system layouts
🔎 verifies the entire tank is serviced — not just “a compartment”

At Allied Septic & Drain, we believe in doing it once and doing it right.

Because “good enough” underground usually becomes VERY noticeable upstairs. 🚽🔥

Another busy week here at Allied Septic & Drain LLC — and we wouldn’t have it any other way. 💪🚽

This week started with getting our brand-new porta potty units prepped and ready for all their new temporary homes across New Hampshire. Fresh units, clean starts, and ready for a busy season ahead. 🔥

We also:
✔ Responded to and replaced a failed sewer pump in an undersized pump chamber
✔ Replaced a damaged distribution box after a patio expansion project accidentally took it out
✔ Repaired a failed septic line and installed a manhole cover so the customer can now pave over the area while still maintaining future access
✔ Continued helping homeowners and businesses keep everything flowing like it should

And to wrap the week up — we got David Jr.’s go kart fully wrapped with the Allied Septic & Drain sponsorship graphics and it came out AWESOME. 🏁🔥

From emergency service calls to installations to supporting the next generation at the track, we’re proud of what we’re building here every single week.

As always, thank you to all of our customers, supporters, friends, and followers for continuing to trust and support Allied Septic & Drain LLC. We appreciate every call, every referral, and every review more than you know.
