Review: Perfect replacement, clear instructions, easy to fit - I bought this to replace a Geberit DVGW 397 which was making a clunking noise every time it shut off. I got a bit confused when researching what I needed, as the threaded pipe that came out of the cistern (the bit that sticks out on the left in the desertcart picture) actually had a diameter of 5/8 inch, and all replacement valves were described as either 3/8 or 1/2 inch, but I eventually found out that the these are the internal diameter of the inlet pipe, so to determine what you need you have to deduct 1/4 inch from the external diameter of the existing unit. Hope somebody else may find this helpful! After all that, the Siamp includes both size inlets anyway, although by this time I knew I wanted the 3/8 size. When it is delivered the 1/2 inch is fitted, so the first job is to swap it over. The instructions are extremely clear and easy to follow, although it is pretty obvious anyway. Fitting the new unit was a doddle, just turned off the water supply, loosened off the nut on the end of the feed pipe, removed the locking nut that held the existing valve in place, and removed the complete unit. Connecting the new unit was a simple reversal of the process, although I did put a few turns of PTFE tape around the thread before reconnecting to the feed pipe. No more than 10 minutes in all, and the new unit is now working perfectly. Fills quickly, and reasonably quietly, and shuts off smoothly. I had never heard of Siamp before, but they have in fact been around since 1947, are based in the UK (Oldham), and specialise in sanitary products.
Review: Good, working well so far, inlet fitting thread 1 cm too long for concealed cisterns though. - I bought this to replace an identical Siamp float valve in my Verso 350 concealed cistern, which unaccountably stopped shutting off when the rising water level closed the float lever. Removing and cleaning and changing the diaphragm did not cure the problem, so thought I'd try replacing the whole thing, as around a £10 outlay is pretty reasonable. Very easy to fit even in the fiddly enclosed space behind the access hatch, and so far it shuts off fine, so seems to have solved the problem [single day experience so far though, so let's see if this continues.] However just as a warning: the brass fittings supplied that you screw the water inlet into turned out to be too long to allow the inlet tap in my concealed cistern to be screwed in. They are 3 cm long while the one in the original valve in mine was 2 cm. The fittings supplied with the new valve seem to be designed to go through apertures in external cistern walls. This wasn't a real problem as I swapped the 2 cm fitting from my system into the new valve-it is detachable and pushes into the new valve with a washer. If you have a concealed cistern you will be able to do the same.

## Questions & Answers

**Q: How does it attach to the cistern**
A: This is a side entry ballvalve. It can fitted in a hole which on the at the top of the cistern. If you have bottom entry cistern it’s the wrong ballvalve. If you look at old ballvalve position it should be obvious. Sometimes you will see a connection in the cistern. Just copy what you see.

**Q: Can I connect this to an olive compression fitting?**
A: Not sure, look at the inside of the brass thread, if it’s tapered an olive will work, wrap PTFE tape round the olive not the thread. The olive make the water tight seal. If it’s not tapered a tap connector should do it if you have the space. You could also use a female thread to compression fitting. Hope it helps. Make sure it’s all watertight.

**Q: What is the distance from back to front (from 3/8" thread end to the other end)? Image says 112mm but not including the thread. Cheers.**
A: If I’m answering your question correctly, it’s just over 6 ins, 153mm. Might not be exact as the end of the threaded brass is covered by a brass nut. I only have a small cistern and most of the brass thread is connected to the inlet pipe outside the cistern.

**Q: does it come with fittings for both half inch and three eights inlets?**
A: I think it does, but it was more than a year ago and I've forgotten!

### ⭐⭐⭐⭐⭐ It was so easy to change...and so reasonably priced!
*by G***L on 21 June 2021*

My Siamp BCM350 Wall Cistern was hissing after 9 years of use. The inlet valve wasn't filling properly. I thought it was going to be an expensive plumbing job and with a Wall Concealed cistern, my husband was regretting our decision 9 years ago, thinking we'd need to tear down the tiles! Anyway, the stopcock in it was jammed...so had to turn the water off to the whole house. Lots of suppliers are charging over £20 for the inlet valve (plus delivery) but Amazon was charging only £11. Ordered and arrived promptly. Husband said order the stopcock as well - just in case...but I hesitated. That's another £12.50 plus postage - nearly £20. So I took a screwdriver and started dismantling. He came up, had a look, and decided to just go ahead, hoping for the best. Once the mains water was turned off, it was easy done - the old inlet valve came out, the new one went in - yes the copper pipe bit was slightly longer - but there was space enough for the longer connector. Took out the stopcock and soaked it in hot water and a bit of vinegar to unjam. All done and dusted. Everything is back to normal.
