High level various plastic cisterns and Blue Circle industries-Armitage Shanks pans refilmed

Was in the area again and happened to needed to stop by so as a result, I've decided to do a re-film of the patient toilets in the Department of Rehabilitation in "Singleton Hospital" in Swansea. This hospital opened in 1968 and has over 500 wards which sadly have been refurbished since then as well as majority of the sanitary ware however some retro sanitary ware remain, even if some of it isn't original, like these blue logo "Armitage Shanks" pieces of sanitary ware here made by "Blue Circle" which was a cement based company who owned many brands such as "Armitage Shanks" pre 1999. What makes this set slightly interesting is, I have never seen a rimless pan like this on a high level cistern in person prior to a couple of years back which was when I first filmed this set. The male toilet has this rimless pan which I am currently unsure what this version of the rimless pan is actually called but it's really similar to the rimless design of the "Contour" rimless back to wall WC pan that used to be available back then, only difference is, this one isn't back to wall and this has a rounded top and rounded pedestal and footprint. It is paired with a "Regal" high level plastic cistern that is branded by "Armitage Shanks" and has an overflow routed into the flush pipe via a tundish which sadly makes the flush worse due to the air inside the flush pipe breaking the suction from the syphon, causing it to be very weak and jumpy. The female toilet has a "Derwent Macdee" high level plastic cistern, which is called the "Rhino" and is now unfortunately discontinued, however the overflow setup is the same as the male toilet and has the same affect on the flush, however this time we have a "Magnia" WC pan branded by "Armitage Shanks" and dates around the dame time as the rimless pan and the basins which I believe are the retro "Portman" range, feel free to let me know if they are actually that as I may be wrong. The flushes on both of these toilets are absolutely dreadful and it's sad to say that even ccpb Chinese toilets can flush better these two, but that's because of the shoddy overflow setup going into the flush pipe which sadly allows air from the syphon to escape when flushing, resulting in a far weaker flush. The solution for a stronger flush would be to replace the flush pipe, rearrange the external overflow pipe and run it into the pan, or block this off with a blanking plug and install an 8 inch height internal overflow syphon. Thanks for watching.
