🚫💧 Think Before You Flush – Protect Your Septic System! 💧🚫
At CST Group, we see it all…one of the biggest culprits behind septic tank issues is wipes.
Even when labelled 'flushable', these wipes don’t break down like toilet paper. Instead, they build up, clog pipes, damage pumps, and can lead to expensive call‑outs and repairs.
Keeping wipes out of your septic tank means:
Fewer blockages
Longer system lifespan
Lower maintenance costs
A healthier, more efficient tank
If your tank is due for a check or clean, the CST Group team is here to help keep things flowing smoothly.
