Drain blocked by calcium buildup

[firapara]

Hi guys,

I have a drain outside of the house which is blocked by calcium buildup, have already tried standard unblockers with no luck.

Is there anything stronger I can try to unblock it?

Thanks,

Maybe hydrochloric acid. If you get concentrated 30 - 35%, I would dilute with 2 parts water. And wear safety glasses!

They can cut stone/cement, they can be quite powerful.

Thank you guys,

Tried hydrochloric acid at about 5-6 parts to 1. Will try less diluted. A bit scared that it is going to damage the pipe.

What's the drain material? HCl won't hurt PVC. Probably also OK with glazed earthenware. It will attack concrete if left there for long.

As someone that uses a Jetter, I can assure you there isn't much they wont remove. Water pressure alone will remove scale and fat, used to drive specialist jetting heads, they can cut out and remove roots, concrete, and pull back bricks, large stones and other debris in a drain.

You certainly dont argue with them, fatalities have occurred.
