CONSERVACAP is designed to provide an easy first step solution to reducing water/sewer costs.  When installed (along with a new Sloan A-38-A Kit) into any standard Sloan or Zurn flush valve,  CONSERVACAP will immediately reduce water consumption from 3.5 gallons to 2.75 gallons per flush.


Our staff has found that the best way to evaluate the performance of a flushometer toilet is to tear up about 50 sheets of toilet tissue and drop it into the bowl.  After the paper has submerged below the water line, flush the toilet, keeping an eye on the second hand of a watch.

Note: Under normal pressure, the standard Sloan or Zurn Flush Valve will run approximately 1/2 gallon of water per second during a normal flush cycle.  A new Sloan !-38-A Kit and pressure cap should have a flush cycle of between 7 and 9 seconds.  This time sequence would use between 3.5 and 4.5 gallons of water per flush.

When the flush cycle begins carefully watch the tissue in the bowl. Once the paper has totally cleared and the bowl is clean, the flushing cycle has achieved its objective.  Now, quickly look back at your watch second hand again; the water that continues to rush through the bowl after it has cleared is now being wasted.  A lush cycle that lasts for a total of 10 seconds (or about 3 seconds after the bowl is cleared) is usually wasting between 1 and 2 gallons per flush, which a flush cycle lasting a total of 15 seconds (or about 8 seconds after the bowl is cleared) could waste as much as 4 gallons of water per flush.


We recommend using the 2.75 CONSERVACAP on most toilet conversion and the 2.5 CONSERVACAP on most urinal renovations.  On an average, this type of change out will reduce water consumption by approximately 1 gallon per flush with the toilets and 1/2 gallon per flush with urinals. The 2.75 CONSERVACAP may be used on some urinal change outs where approximately 1/4 gallon more water may be required.  However, with very few exceptions, we do not recommend that the 2.5 CONSERVACAP be used on most toilet fixtures.

Those few exceptions, where our staff has found the 2.5 CONSERVACAP to provide effective performance on toilets have occurred with “blow-out” type fixtures (where the incoming water is brought at great force into the bowl from holes located in the front side of the fixture).  A few other types of fixtures such as the American Standard Aft-wall can also flush extremely well using just 2.5 gallons of water.  Because functionality is the most important requirement of any water renovation, we recommend when in doubt, us the 2.75 CONSERVACAP.

We also recommend including new toilet or urinal kits when installing the CONSERVACAP.   While our cap will always reduce consumption, because the diaphragm and the pressure cap wear to fit each other over years of use, the maximum savings performance is best achieved by starting out with all new components.
