## Questions & Answers

**Q: Can you extend the air line on this with a adapter or air line to prevent having to access the confined? what connection would be needed on the line?**
A: Just have a long car airline

**Q: would this bag seal off a 110mm soil pipe?**
A: Yes, these are designed for that purpose and will suit the 110mm pipe. I hope this helps. DQ Services.

**Q: Can i use the 6 inch ballon in a 4 inch pipe ?**
A: Hi. No you cannot use the 6" Drain Bag in a 4" Pipe as the Bag will not be able to form it's shape to create a seal. Use the PVC 100mm/4" Drain Bag for 100-110mm Pipework etc..

**Q: Which size should I purchase, 4 or 6 inch, for a standard toilet?**
A: 4” as it inflates a bit and fits the standard 110mm pipe

### ⭐⭐⭐⭐⭐ Great

### ⭐⭐⭐⭐ 4" inflatable drain bag
*by T***T on 24 March 2019*

these are very good bags but i have found with use they tend to puncture easily, as yet i have not been able to repair one successfully and at around £20 per bag if not more that is not good, you want them to last long enough to return the cost of the item and also earn you money on the job every day
