5 Signs Your Septic Tank Is Failing

A failing septic tank usually warns you first. Here are five signs worth acting on before it becomes a big job.

A septic tank rarely fails overnight — it usually gives you warning signs first. Catch them early and you can often avoid a far bigger, costlier job. Here are five to watch for.

1. Slow drains throughout the house

If sinks, baths and toilets across the property are all draining slowly, it points to the system rather than a single blocked pipe.

2. Bad smells outside (or in)

A persistent sewage or rotten-egg smell around the tank or drainage field is a classic sign that something is not flowing or breaking down as it should.

3. Pooling water or extra-lush grass

Soggy ground or a patch of unusually green, fast-growing grass over the drainage field often means liquid is surfacing instead of soaking away properly.

4. Gurgling sounds

Gurgling from your drains or toilet when water runs away can mean the system is struggling to cope.

5. Needing emptied far more often

If your tank is filling up much quicker than it used to, something has changed — often a failing soakaway backing the system up.

Spotted one of these? Do not wait for a full backup into the house. The sooner it is looked at, the more options you have and the cheaper the fix tends to be.
