The slip feature makes this valve ideal for retrofitting or replacing existing pressure regulators.

Rated 1 out of 5 by from Poor pressure reduction; sometimes leaky We bought some of these to use in replacing the pressure valves at our business park. Not only have we had issues with them leaking where the rubber meets the metal, they also hammer the pipes. When tested with a water pressure gauge, they were measuring 100psi. There was nothing being reduced. Not only this but getting them off the pipe is a nightmare! We needed two people to do it! We returned them and went to Watts. When we installed the Watts, there were no further issues with the same PSI rating.

Rated 5 out of 5 by from 10 min install. Great product We have an older home (1940s) and have been experiencing water hammer for a long while. I've tried everything to fix it. On a whim I finally checked out water pressure, and it was 120psi! Way above and beyond the safe level. I found this product, and having used sharkbites before, I went and grabbed one this morning. Took 10 mins total (high estimate on time). Water pressure immediately went down to 45psi. Great product!!!

Rated 1 out of 5 by from Crazy Hammering I simply installed this as a precaution after experiencing a leaky faucet from high pressure. The price was right and the project simple enough based on some consultation from Home Depot. I have never experienced hammering pipes until after the install. Now, it's like a machine gun going off all throughout the house when you turn on the shower and flush the toilet. It was the shower and the washer, but I installed reducers to help with the washer. Now, after two weeks of trying to figure out how to solve for it, I started researching how to simply put it back to where it was. I came here to see if anyone else had issues. That's when I saw the other two reviews that are almost the exact same problems I am having. When it hammers it also is leaking between the black ring and the metal. I would not recommend this product, though the Shark Bite technology is about the coolest thing a non plumber could hope for.

Rated 1 out of 5 by from Water Hammer I installed the first one after three days of use had a severe water hammer luckily I had a bypass installed. When bypassed hammer was gone. Returned regulator to store and exchanged for a replacement it worked for two months and water hammer is back even worse this time. Will remove this and go back to the Watts that I had on for over 10 years. Nice idea but poor quality.

Rated 5 out of 5 by from The sharkbite make installation a breeze The product works as described. The only issue I have is that the directions don't give you dimensions to cut your pipe to. They want you to buy a gaging device. I didn't do this. Just used a caliper and took my own measurements. The sharkbite fittings worked great with no leaks. Much easier and cleaner than soldering the joint.

Rated 5 out of 5 by from Love the Sharkbite I was installing this on PEX piping. After a few measurements and quick cuts, it was in with no leaks. Sharkbite products may be more expensive but it always works for me as promised.

Rated 1 out of 5 by from Dont Do It!! I bought this today and it is a joke. the reducing mechanism is crazy small. It hammered worse than the old one I took out. My God! When I tried to remove it and replace it, we could not get it off to save our soul. Slip Joint??? Don't do it! buy a zurn or watts and 2 3/4 sharkbite MIP adapters. Trust Me!!!!!!

Rated 5 out of 5 by from Works as advertised I ordered this pressure regulator to reduce the incoming water pressure in my home from 56 psi. I checked the water pressure prior to installing the regulator and after with a reading of 40 psi which was 5 psi lower than the stated rating from the factory. However, the psi is adjustable, but I left it where it was. Regulator was easy to install with the push to fit Shark bite fittings. I used pex pipe with my connectors.

i bought the EB45 DSB, but and want to install on a straight copper 3/4" pipe, but the instructions do not say how much pipe i need to remove. Also, i do not have the slip version, which is the one that says it is best to use. Why?

Asked by: Joeyd0315
Hello, For the 3/4" EB45 DSB (part# 23808-0045) you will need to remove 2.23" of pipe. This is determined by subtracting the insertion depth (1.125") for each side from the overall length of the valve (4.48"). If you do not have play in your pipe you will want to go with the slip version, which will assist you in sliding the valve into a tight space. Best regards,

why is there an asterisk after 'Lead Free*' on your box?

Asked by: San P
Hello, The asterisk on the box corresponds to a proposition 65 warning located in the installation instructions regarding lead. The warning reads "This product contains chemicals known to the state of California to cause cancer or birth defects or other reproductive harm. Notice to Installer/Contractor: California law requires this notice be provided to the consumer/end user of this product". All brass plumbing products by all manufacturers, even the ones considered lead free, contain at least a small amount of lead for manufacturing purposes. The law requires there be less than .25% by weight in order to be considered lead free. Thank you

24384-0045 I bought and installed this pressure regulator and now my water is pulsating and my pipes are banging. I have seen three other reviews that this product is know for this  how are you going to help me with this problem?

Asked by: freefall
Greetings Freefall, The EB45 is a compact valve. The only times we have heard about this vibrating or pulsating was when it was installed in a high flow system. This doesn't happen every time it's in a system like that, but when it pulsates, it's due to that system. You can try increasing the PSI threshold on the valve. If that does not work, we do offer larger valves that handle higher flowing system better such as the EB 25. You can view this product at this link: If you have any questions or concerns, please feel free to reach out to our customer service team at 1-877-700-4242 Monday - Friday from 8 am to 6 pm est.
