Toilet - what water???

[ptarling]

Any help appreciated.

Just a quick one. Can I use the water from the hot water tank to supply the cistern on the toilet or does it have to be mains fed?

You mean use water from the cold water storage cistern which feeds the hot water cylinder? Yes, it doesn't have to be mains fed.

Yep I meant the Cold water storage cistern.

Thanks very much

Thats where it should come from

Nothing wrong connecting to the mains if you have a combi system or unvented hot water.

Where the water comes for the toilet is not dependant on your heating system.
It might be dependant if you have no storage facility.

Correct, what I meant was, with those systems there is no requirement for storage water therefore wc cistern is mains fed.

Ive noticed some modern toilets fill up in seconds, -would these need mains pressure to fill so fast?

For low pressure use, you may have to modify the ball valve. Some of the modern valves don't come with a low pressure option - you may to have get a different optional washer or something to achieve a reasonable flow.

....yes, and it`s all a lot better than the old L.P. ballvalves .......so 19th. Century

If you are going to use tank fed water then you will need to use the Low Pressure jet provided with the ballvalve. Torbeck valves and the like dont work well and are not designed for tank fed water.
Theres no rule saying it has to be fed from the rising main however this is invariably the best option.

you`ve not experienced the joys of the Croydon ballvalve then........or the local bylaw appertaining to a seaside town known for it`s aged populace .....whereby a wc had to have a break tank to supply it with l.p water ....pulled a few out B4 now....even Thos. Crapper would`ve been amazed
