## Questions & Answers

**Q: does this come with the seal (part number 5 on your diagram)**
A: part 5 is part of the cistern, so it can be re-used or replaced with a new one. We only needed the main body and so didn't change the seal numbered 5

**Q: Does this come with the seal?**
A: Yes it did

**Q: would this fit a Gala cistern?**
A: Does this two Twico-1 main body plug in and do a quarter turn to lock it in place

**Q: Hi which of the dual flush valves do I replace mine with mine has no makers name, so how do I know which one to order**
A: Hi there, 

We cannot advise you on which part to order if we don't know which Cistern you have.  Perhaps take a photo of your cistern and email it to our technical team www.showerspares.com?
