Review: 7/8 inch inlet - Reading other people's comments on being the wrong size is exactly why I bought it!! The inlet fitting is 7/8 inch(22mm) , fitted straight out of the box, just had to adjust height . Worked a treat. Again, the inlet is 7/8 inch, measure your original inlet pipe to be sure.
Review: Not suitable for British plumbing - Pipe thread does not fit English plumbing. Too big to go through cistern hole and won't fit standard plumbing size.

## Questions & Answers

**Q: What is the difference between the 400H and 400AH?**
A: The 400H is the newer version of the 400AH. The bowl water adjustment on the 400H is integrated into a knob in at the top of the flush valve. On the 400AH, a roller on the refill tube adjusts the bowl water level.

**Q: Can i use this to replace a delta toilet fill valvepart RP71188?**
A: The 400H-002 will replace the Delta model. The 400H can adjust to the same height and comes with an adjustable bowl refill knob to control the amount of water going to bowl. With this adjustment you should be able to match both bowl and tank water levels to the original levels.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 7/8 inch inlet
*by D***L on 15 August 2025*

Reading other people's comments on being the wrong size is exactly why I bought it!! The inlet fitting is 7/8 inch(22mm) , fitted straight out of the box, just had to adjust height . Worked a treat. Again, the inlet is 7/8 inch, measure your original inlet pipe to be sure.

### ⭐ Not suitable for British plumbing
*by M***Y on 28 July 2025*

Pipe thread does not fit English plumbing. Too big to go through cistern hole and won't fit standard plumbing size.

### ⭐⭐⭐ WARNING! Not for UK toilets!
*by I***D on 14 August 2024*

I fell into the same trap as others did (I realise now, reading their reviews): this is made for US plumbing with a 7/8 inch BSP inlet pipe (I think that's the measurement - it doesn't actually say, and that is the problem). So it's "universal" for American plumbing, but your UK inlet pipe will probably be too narrow to connect to it. Apart from the total lack of compatibility, this seems like a good product. But why is it being sold in the UK?
