Review: Quiet and sturdy fill valve - Bought as a replacement for a cheap generic fill valve that gave up. Slimline cistern but plenty of space, brass inlet pipe is offset and can be used with inlet hole close to wall of cistern (see pic). Measure the height from the floor of the cistern to the top of your overflow pipe and adjust the height of the fill valve accordingly, aim for the CL line/overflow nozzle to be about 1" above the level of the overflow pipe. I found it easier to adjust before install. Note: the overflow tube that runs between the fill valve and the overflow pipe is not included here, make sure to keep the existing one when installing. Hand tightening the fixing nut was enough for a good seal, the tapered rubber washer is good quality. Note that the fixing nut has side flanges to help with tightening, but they do not extend above the level of the nut, so if your fitting is inside a recess you may struggle to fit fingers between the nut and the recess wall, but as a standard size you can use the old one if it is easier to tighten. All in all, great product; simple to fit, quiet fill operation and great value, would buy again!
Review: Excellent product which is straightforward to install for non plumbers like myself ! - A very efficient and effective bottom fed cistern flush unit. It took me slightly longer than other reviews to install at nearly an hour [ which did include the removal of the existing unit ] The installation instructions [ on the box container ] were straight forward, concise and easy to follow. The I design and easy water level adjustment are quick and simple. Like other reviewers i found it better more an access point of view to adjust as near as possible before placement of the flush unit in the cistern.

## Questions & Answers

**Q: I need a bottom entry fill valve with a shank of at least three inches. Can you please confirm if this has that?**
A: The valve is actually telescopic and so extendable to the required height of pretty much any cistern. If you look closely at the image you will see that the lower portion of the valve is narrower and fits inside the upper portion. You can take a small clip out of the assembly middle and then raise or lower the top section to make it exactly right for the cistern that you are fitting it to. I believe you will find this a suitable replacement for just about any bottom entry valve. I fitted it to a modern dual flush cistern that was only a year old (very hard water area so the original clogged) and it works a treat. Hope that helps.

**Q: I have a top flush cistern with old ball cock filler can I take all that out and this would work??**
A: I replaced an old ball cock with one of these. However mine was faulty and did not  fully close off the water when the cistern  was full so caused an overflow. I ended up getting a similar thing from Wickes.

**Q: Is the water meant to come out of the spout at the top, as the one we have just fitted it seems to fill through the body?**
A: No the water does not come out of the spout, I'm not even sure what the spout is for. Mine also fills through the body.

**Q: Water falls below cistern mark shortly after flushing no water leaks.Is this normal**
A: sounds good to me but you can unscrew the water ajuster to allow more water to enter if needed

### ⭐⭐⭐⭐ Easy to fit and adjust, read the instructions
*by D***. on 18 March 2024*

Replacement for cloakroom toilet flush which died. Know little about these things but took a punt as inexpensive and sturdy looking. In fact was easy to install though needed a couple of tweaks to ensure cistern filled to correct level and has been working without issues for about a year now. Do measure the cistern to ensure it is going to fit before purchasing!
