Siamp 99T Bottom Entry Adjustable Telescopic Inlet Float Valve 1/2 inch 15mm Plastic 30998010, Multi-Colour

Have a slimline en-suit bathroom fitted and the cistern filler was a mare to adjust and was possibly not the right one for the job... the unit was large inside a slimline plastic cistern that had strengthening braces further restricting available space... after many years of use, it failed.. as did the overflow system and flooded the place. Bought this to replace the old (also replaced the overflow/flush mechanism) but this unit is smaller than original one and fitted perfectly into the cistern and did not foul on anything inside. Took about 20minutes to remove old and replace with this. The instructions were clear enough and some marking and measuring is advised to assist with a very simple setting of this unit's height prior to installing.. takes a few minutes only and worth it. First fill was spot on to what I needed and the unit needed no further adjustment of water fill level... flushed and it filled spot on.. quieter than the old one and no slower. Several weeks later.. it still fills to exactly the right level.

Two of the inlets in my toilets started getting slow and noisy at the same time.Bought these to replace them and was surprised at how easy it was. Had fears of leaks etc, as my existing ones had been siliconed in place, but these fit fine, no leaks, even without silicon.Much faster than I ever remember my last ones being too, and very quiet.

excellent, fitted in a very short time, easy to follow instructions, most of fitting common sense. loo now working properly.

Easy to fit, loo works well now!

Works for purpose

Good quality, adjustable.

The package did not arrive at my address, it was dropped off somewhere else. The seller sorted it out.It has now been installed and works perfectly. Many thanks.

Instructions left a little to be desired but only a little. This is a well constructed product that provides a reliable fill under a range of pressures (adjusted using the cistern fill isolation valve), is quiet while filling and shuts off cleanly. The construction overall is really very good - good design, plastic with clean edges and solid where required. The fill level adjustment is a bit fiddly and a good hit would probably be able to damage the flow shut-off.The fitting requires (noted as mandatory) the appropriate backflow prevention device on the feed pipe. Regarding various comments about water coming through the top end, this isn't supposed to happen - there was a little of this on the first initial fill but it closed off immediately and fills perfectly every time when fitted/operating as designed.
