## Questions & Answers

**Q: can i use this with a septic tank?**
A: I don't have a septic tank but I do have a "Biodisc" digester instead of mains sewerage. I've used Duo four or five times over about the same number of years and it has not caused any problems. It also does the job far better than anything else 've ever tried.

**Q: Can use this for the toilet? Would it damage the white ceramic bowl?**
A: Good afternoon,

Please be informed that HG "duo unblocker" must not come in contact with the ceramic bowl. It must be pourred carefully in the drain, to avoid any damage of the surface.
However in case of a toilet we can not guarantee that the blockage will be solved. The blockage could be too far away or the product will be diluted too much by the water in the toilet drain.

**Q: is this suitable for outdoor drains?**
A: Good morning,
Please be informed that this product is not suitable for outdoor drains.
We do not have an alternative product in our product range which can be at your assistance.
Trusting that we have informed you sufficiently,

**Q: Can this be used in a washing machine? to help clear hair blockage?**
A: No, this is not suitable for use in a washing machine or dishwasher.  We would suggest using HG Service Engineer which is designed for use with washing machines and dishwashers.
