## Questions & Answers

**Q: Are the pipe fittings 110mm or 160mm?**
A: They are 115 so you wlll need some uk pipe and the rubber couplings with clips  which are 115 to 100 to connect to French 100 mm pipe

**Q: Will uk 110mm soil pipe fit straight onto this and how many section will i need to get to 500-550mm from bottom of gully to top of cover. i**
A: This is designed for 110mm pipe. The total height (external) is 580mm. Removing 1 of the 2 risers would reduce this figure by 150mm.

**Q: Will it fit 80mm perforated pipe?**
A: Yes. The diameter of the inlets are 110mm, so an 80mm perforated pipe would fit inside. You wouldn't need an exact fit using a perforated pipe in any case.

**Q: What are the dimensions and do 110mm soil pipe fit straight on this**
A: Yes standard plastic drain pipe fits directly
