OpellaToilet Delchem Cistern Bottom Entry Filling Valve Adjustable Arm 1/2" with Float Plastic Float Valve

Well made but does not fit all bottom entry units because there is not a way provided to move the float ball along its arm in order to miss coming into contact with the flushing chamber. Please check to see if yours is the same type as this before you purchase. Otherwise this is a good product.

Fitted perfectly and easily installed. Although not my immediate need - the old one wa noisy/vibrated - this one also fills the WC cistern twice as fast. It's also cheap.

Works well, solved my problem with slow filling system.

Well made, fits well, easy instructions, good quality parts, fast delivery would buy one again 👍

Perfect for my needs and fast delivery

A reasonably priced replacement part that will do the job and is easy to install without instructions. My only gripe (as other reviewers have mentioned) is the cheap/poorly made parts which result in water spurting out of all the seals (in addition to the nozzle designed for this) upon flushing. I did attempt restricting the incoming water flow, which does reduce this problem but... this also results in a very noisy (admittedly still effective) flush, so not really suitable for an en-suite (or in my case, a B&B en-suite). Fitted correctly, with the cistern lid in place, it doesn't seem to be a huge issue as the lid contains all the water that is effectively spurting everywhere when you flush the toilet.

Product seems good and works. Took me a while to counter a leaky valve. It would be really helpful though if they could include a simple diagram of how the partners fit together as I expect plenty of novices order these and mine came it about 10 different parts down to little plastic items and I had no idea how they all fitted together, even after watching videos... Hence the initial leaks as I worked it out.

Ideal for all sized toilets. Great value for money! And this completely stopped my drip from the original one previously fitted!
