Does this backflow preventer reduce the water pressure?

I experienced a significant reduction in water pressure - enough that my sprinklers won't work properly with the device connected. I had to disconnect it. I keep looking for someone to manufacture a "full-flow" backflow valve that will not reduce water pressure, but I haven't found it yet...

Not at all. I own a RV park and installed 24 of them and they work perfectly. I don't use the set screw because it buggers up the threads if you want to remove it

Yes. When you shut the water off some of it will come back and splash out of this attachment (and get your hand wet). This is a good thing. Just dry your hand and be glad that the pressure has been relieved from your hose and other more expensive attachments you have at the spigot (e.g., timers).

I haven't noticed reduced water pressure, but we are lucky to have plenty of water pressure in our area, so I think it will be hard to notice for us

We experienced no reduced water pressure in our fifth wheel after installing this blackflow preventer.

Yes-- the water pressure will be reduced some as compared to a bigger dia. hose.[That is physics ] However, if you have very good [i.e high] pressure to start with, it will not be a very notable reduction. If your pressure is not very high to start with, the reduction will be much more noticeable.

I dont believe it does, and if it does it is easily removed. The more water pressure you have the better the shower head works. Its cool....

if you are thinking of installing the filter system on the main water line, I think it would reduce your water pressure greatly.

I bought a set about two years ago, and it did not included a pressure reducer. So, you better buy one separately, or you'll risk blowing out holes in your soaker hose.

Yes, it reduces the pressure a little and during backwash you can only get a trickle of water, I set mine to backwash at like 2am and iv never had a problem. but it works great the scent is gone.

It does if you have the faucet fully open. reduce the flow to solve the problem.

It does. It really works well. If your water pressure is to high you will need to hold it. But works very well

Yes it does. The rubber O-ring that seats between the top to the bottom effectively eliminates loss of fluid.

No it does not. It works the exact same way the pull drain stoppers work regarding sink overflow. The Push and Seal is a really cool and innovative product that adds a nice look to the faucet and sink.

Yes it closes the flow but I wouldn't recommend this product. It is made cheap and doesn't have much pressure. I guess you get what you pay for.

No it does not decrease pressure, simply diverts the water from the shower head to a hand held side spray

I am not an expert. I have mine hooked up to the Natural Gas company line that has a meter on it. I think it reduces the pressure.

Actually I think it improved our water pressure. We have a well and our water pressure is very limited. I think it worked better after I installed the new head. There is a water restrict or inside the head that I removed for our shower and left in for the kids.....I didn't notice a significant diff.

It works with a lever that gradually increases the water volume. You push it forward or back. It stays where you set it without having to hold it. I like being able to reduce the spray for the head and face.

I have the stainless steel one, and yes, the pressure seem diminished slightly. Not sure if it's a 'green' low flow feature.

No. It is only a simple check valve for a water hose type system. If you want to reduce the water pressure, then you would need to insert a restrictive rubber washer or else get a pressure regulator.
