Five Frequently Asked Questions
How does the Conservacap actually work?
ANSWER: The size of the inner cap cavity is minutely smaller than a Sloan or Zurn Cap. The difference in the blue and red cap is less than .002 of an inch and it equates into a ¼ gal of water savings. When the cap cavity becomes filled with water, the flush cycle ends. This shorten flush time, usually by several seconds, creates the savings. It does not affect the pressure or force of the water flow in any way. The fixture flushes just the same as it always does. It just shuts off sooner. Anybody that flushes 40 sheets of toilet tissue and watches the bowl clear, and then watches four or five seconds of water continue to run through the system can understand the basic principal.
How can a plumber be assured that there won’t be additional maintenance issues from using Conservacap?
ANSWER: The best way is to install several in your most active restrooms and watch their performance. Also, most plumbers appreciate the fact that the product was designed by plumbers who were doing turnkey installations and did NOT want to have call backs. Many plumbers are also concerned about installing new 1.6 gpf low flow fixtures into older sewer systems. This was the case in Nashville Airport project. These folks have 400 toilets flushing a couple hundred times a day each. That’s pretty good testing.
How does reducing flow of water actually improve performance of the 3.5 gpf toilets?
ANSWER: Again, Conservacap DOES NOT reduce the flow of water. The flow, force or pressure of the water is all the same, before and after. The flush cycle just ends sooner. Conservacap improves the performance of the fixture by making it function more efficiently. We don’t make it flush harder or any better than it did before. We say it flushes as well with less water.
How important is it that a new repair kit be installed with each Conservacap?
ANSWER: Conservacap will always save water when you install it. We know that we have had thousands of Conservacaps installed in older systems without benefit of a new A-38-A, or A-37-A repair kit. If the diaphragms in your system are in good shape feel free to simply install the Conservacap. Because the cap and diaphragm work and in many cases, wear together, to assure optimum performance we recommend installing a new kit at the same time the conservacap in installed.
How does the use of auto flush units affect the water savings one might get with Conservacap?
ANSWER: Auto flush units do not normally change the amount of water you use per flush; they just increase the amount of flushes. So, contrary to saving water, facilities converting to “No Touch Systems” are always going to see their water usage go up. In fact, if existing Sloan or Zurn 3.5+ gpf fixtures are converted to “No Touch Systems” (usually done by replacing the existing handle kit with an auto flush unit) a considerable increase in the amount of water consumed will occur. This is particularly noticeable in schools where many times less than 50% of the students flush on a regular basis.” In these cases, the additional benefits of saving water with Conservacap will become very obvious.”
