We (ie on Sanity) were just coming to the conclusion that the uric acid 
explanation was more likely all told, especially as we've not seen 
massive amounts of scale in the kettle, on the shower head and so on. 
With the water feed to the loo choked back to the minimum to achieve an 
adequate bowl clearance (so as to increase the inter pump out 
interval), there is probably a similar situation to the gents urinal in 
the macerator. Probably the fact that some of us take calcium carbonate 
supplement as a prophylaxis for osteoporosis doesn't help...

What we need is a trial with some of the scale and the various 
compounds proposed as treatments.

Cheers
