田忌赛马谁为田忌出的主意

URIC XTREME? does indeed work. In fact, URIC XTREME? is now guaranteed to clear a urinal blockage. If you are not completely satisfied with the performance of URIC XTREME?, we will simply and quickly refund your money.

Both URIC XTREME? and URIC? FREEFLO are safe to use on all ceramics, plastics and metals - including copper. But a word of caution: The build up of uric scale deposits in copper pipework can lead to corrosion. If this is the case: no leakage will occur all the time the gaps are filled with the scale deposits. But, as soon as the uric scale is removed - the holes will appear. So, although URIC XTREME? and URIC? FREEFLO will not corrode copper pipework themselves - as explained above, if the pipework is very old, the best course of action may be to replace it.

Normally, a total application of between 1 and 5 litres will be sufficient to clear a urinal blockage. Start by pouring approximately 1 litre of URIC XTREME? into the urinal bowl or trough, and wait for this to run away. Repeat this after approximately 5 minutes (if necessary) - until the urinal flow is back to normal. There is no need to flush with water.

URIC XTREME? and URIC? FREEFLO can be used in a bio-tank. Both products are extremely fast acting, and are poured directly into the urinal. By the time the products reach the bio-tank, they are dilute enough to cause no harm.

URIC? FREEFLO is used neat. It is usually dosed manually (but can be dosed via an automatic dosing pump). MANUAL DOSING: Simply pour between half and 1 litre of URIC? FREEFLO directly into each urinal bowl/trough once per month. As an example: Chemassist? maintain the urinal systems for most of the theatres in London. We manually dose around half a litre of URIC? FREEFLO per urinal, per month. Considering the large number of visitors to the theatres, half a litre is sufficient to keep the urinal system clear of blockages and free flowing.
