Cistern with an integrated sink

Q: How can I buy the adapter piece for a close coupled toilet pan?

2" BSP Close coupling kits are widely available. The purpose of a conventional close coupling kit is to hold a ceramic cistern and pan together. On this plastic cistern the spigot outlet can be placed into a modern inlet to a toilet bowl. The fitting will be spigot /socket flowing under gravity i.e non pressure, the outlet is lower that the inlet and so leakage is not a risk at this junction, however a 2" donut foam seal is advised (Screwfix/Toolstation). The weight of the cistern would be transferred to the pan. The supplied wall bracket would hold it to the wall.The foam seal would ensure no leaks. A conventional close coupling kit could be used although there is no clear benefit. If it was used slot onto the 2" outlet, screw the 2" backnut, drop the cistern into position an tighten the wingnuts which would provide further fixity to the pan.

Q: I've read that there is a version 2 of this with an improved tap, are you shipping the new version or the original?

We are supplying what could be described as V2, this has the improved tap. The improved tap is stronger and will not rust. Many thanks

Q: Where does the water feed into the cistern?

On the left hand side base you you will see the spigot in the image. This is the main water in feed and is attached to the inlet valve. A competent Diyer or plumber could swap this over and cap the hole if required - this would require drilling the plastic cistern body. A simpler fix would be to modify the inlet pipework :).

Q: Help! i have correctly connected tap via plastic tube but cistern is filling very very slowly and somehow bypassing the tap when filling. how to fix?

i can't tell you how to fix it, but my cistern fills promptly when you press one of the two buttons. i had a plumber install it. you should ask a plumber. i am personally very pleased with my purchase.
