Rated 5 out of 5 by Just the Job Replaced a seized up valve and works fine. From other reviews, I expect it to be reliable as well. 28 Nov 2015
Rated 5 out of 5 by excellent Great replacement at a very competitive price. Would fit again. 21 Aug 2015
Rated 4 out of 5 by good valve easy to install but can be a bit noisy at low pressure the valve sound like bee or wasp trap somewhere don't know how long it will last due to plastic/nylon internal part 16 May 2013
Rated 4 out of 5 by Not silent Works ok but the surprising thing is that it is quite noisy. More of feature than a bug since you then know you have left the outside tap on. 27 Dec 2012

Answer: 
Hi Tome. Because this is a double check valve, we would not expect it to have the same flow rate as a full bore product. I hope this information is of help to you.

Answer: 
Hello,

A Double Check Valve consists of two check valves to ensure that one check valve will activate even if the other is jammed wide open. Also it allows the closure of one valve to reduce the pressure on the other allowing a more reliable seal.
