## Description

WRAS Certification - 2" and 1.5" bases, adjustable integrated overflow

Review: Works well and easy to fit - Installed this dual flush outlet valve to replace a worn original. Fit was correct for a 2-inch outlet and installation was straightforward. Flush performance is strong and consistent, with no leaks so far. Good replacement part.
Review: Compatible with AFV40100 and AFV40200 bases - For those who are wondering if this will replace the now out of production AFV40100 or AFV40200, the answer is YES it will! It was a direct swap, no need to dismantle the cistern just twist out the old body and fit the new one. If your toilet isn't refilling and constantly dripped water then this is for you. It wasn't clear to me if I could simply remove the top half of the old cistern valve, and replace it with this new one so I took the plunge (pun intended). I'm pleased to say that the whole process took me all of 2 minutes! I took pictures along the way in the hope it'll help someone out there. It was a direct swap, no need to dismantle the cistern just twist out the old body (I had to twist mine CLOCKWISE) and fit the new one. As for the dual button it doesn't sit proud by 5cm as others have said, it's completely flush. The chrome fixture needs to be twisted apart and each side sides either side of the lid and is screwed on. I've tried to include as many pictures as possible in the hope all this makes sense and hopefully prevents you from having to pay for a plumber to visit. I hope you found this review helpful.

## Questions & Answers

**Q: Is this the afv50100/50200 model**
A: Yes- it is exactly that. I purchased an extra one in error and it has those numbers on the base. 
You’re welcome to it if you happen to live near Bristol !!

**Q: Would this fit a 6l compact concealed system**
A: Not sure as there are a number available. If you can get to the current outlet valve there should be a maker's name and part number somewhere on it. If not, try the local plumbing supplies shop for advice.

**Q: Replacing macdee afv40100/afv40200, would this be suitable?**
A: Hi Marcela,
Yes, the top section of the valve is compatible with the now discontinued AFV40100 and AFV40200 models and simply fits into the existing cradles without removing the cistern.
The top of the valve has the codes AFV50100 and AFV50200 and comes complete with an adjustable overflow tube which adjusts from 190mm to 330mm.

**Q: What is the Cable length**
A: Hi

This item has a Cable length of 400mm

### ⭐⭐⭐⭐ Check overflow setting when installing.
*by J***L on 8 September 2022*

Carefully check overflow when installing. Factory setting would, if overflowing, lead to water spilling over into bathroom rather than toilet. Easy fix, just be aware.
