One of the first signs that your pipes may need relining is the occurrence of frequent and persistent blockages. If you find yourself dealing with recurring clogs despite attempts to clear them with traditional methods like plungers or drain cleaners, it could be an indication of underlying pipe damage.

Does water take a long time to disappear down the drain? If your sink, shower, or bathtub is exhibiting sluggish drainage, it could be a red flag indicating pipe damage.

Cracks or fractures in the pipes can obstruct the smooth flow of water, causing it to back up and drain slowly.

These noises often occur when there’s a blockage or damage in the pipes, causing air to get trapped and create those peculiar sounds. It’s a sign that something is amiss in the plumbing realm.
Toilet Bubbling is also a sign of a potential toilet blockage.

Foul Odours from Drains
If you notice a persistently foul smell wafting from your drains, it’s a strong sign that your sewer pipe might be blocked.
The smells are a result of blockages that prevent wastewater from properly flowing away, causing it to sit and stagnate.
In some cases, you might notice these smells even before you see issues with your drains. So don’t just brush it off as a one-off event.
So if you’re picking up foul odours from your drains, it’s time to consult a licensed plumber. After all, it’s always better to be safe than sorry, right?
