constant use toilet flushing

[Gillian]

I run a community centre and when we are very busy with special events the toilets form a queue but the cisterns do not refill quick enough between users to be flushed - is there a way to increase water into the cistern - how do motorway services or big event venues like the O2 do it? I have one set filled from the mains and one set filled from the header tank. It is the header tank side that is slowest. Can I fit a pump or have a second cistern that drops its water into the first tank after a flush so it is immediately ready to flush again? Or a cistern in two halves so it flushes one side and then the other? Do these things exist? It is important to have enough water with each flush so the drains then do not get blocked.

Yes you could fit a pump
or just better still change it to mains the same as the other one

Big places like the 02 are designed so that your problem does not happen they have so many toilets per max capacity and big mains break tanks and pump sets

You say you have 2 sets which I guess is the Ladies and the Gents, how many toilets and basins in each room? Any room above for tanks? Also registering as a member helps.

Re the tank fed cistern.

Check the orifice, (plastic thing with small hole in it), it's probably too small (1/2" X 1/8" HIGH PRESSURE BALLVALVE SEATING SEAT X 5 | eBay)

Needs to be a Red or have at least a 5mm hole in it. Ball Valve Seating Cone Low Pressure Cistern Loft Tank Float Valve* | eBay


If it's a part 2 ball cock, (Part 2 HP 1/2" High Pressure Brass Ball Cock Float Valve Ballvalve and Arm only | eBay) replace the diaphragm, it's probably gone stiff. http://www.ebay.co.uk/itm/2-x-Ball-...202?pt=LH_DefaultDomain_3&hash=item2a46282bca
