How do I release pressure before/while removing both test caps from R22000? Both of my previous tests resulted in one of the caps being shot across the room along with a stream of pressurized water!

Asked by: loski
Thank you for your question, loski! The purpose of the test cap it to ensure water flow is directed appropriately to the shower head, hand shower or jets that are installed and that there are no leak points. Before this is accomplished, however, the valve flush should be performed. It is recommended that the water is turned off to this unit, room or home prior to flushing. Once the water is off, the test caps can then be removed and you can turn the water back on slowly until reaching a full, mixed flow, flushing out any debris for up to a full minute. Best regards, Edward

what is this used for?

Asked by: peggie
Thank you for your question, Peggie. This cap is used to test the plumbing connections for leaks and flush the lines before installing the cartridge. If you have not purchased a trim kit yet and do not have a cartridge, the cap can be used along with a Test Plug (RP46079) to allow you to leave the water supplies on to the valve without experiencing cross flow. Best regards, Jon
