Has some construction issues
Fantastic
I would buy this product again
Fast delivery!
Excellent Product - Easy Install, Great Performance
I would recommend this to a friend
Good product, easy install.
I would buy again
Would buy again, but only from SupplyHouse.com
The 25 AUB is the better choice
Would have been nice if order wasn't missing anything!!
Product Q&A
22 QuestionsQ: Is a backflow valve recommended to be installed with the pressure reducing valve? It's illustrated in the instructions but I don't see any in the customers photos.
Asked by CW 2 years ago

Verified Reply- SupplyHouse StaffHello, thanks for writing in. Yes, a backflow valve is recommended to be installed in line in the system along with the PRV.
Q: What thread size is the gauge fitting and does it measure outlet or inlet pressure?
Asked by Adam 7 years ago
Add your answer
Verified Reply- Supplyhouse.com TeamThe valve is 3/4" threaded inlet and outlet. The pressure range is 25 to 75 psi with the Max inlet pressure of 300 PSI but it does not measure the pressure, for that you could use a pressure gauge which you could find here: https://www.supplyhouse.com/Temperature-Pressure-Gauges-864000
Q: do you tighten the screw down for more pressure?
Asked by ken 9 years ago
Add your answer
Verified Reply- SupplyHouse StaffFrom the installation instructions, "Regulator is factory preset to 50psi (344 kPa). To adjust pressure setting, loosen the lock nut and turn the adjusting bolt clockwise to increase pressure, counterclockwise to decrease pressure."
Q: What pressure should be on the outlet side?
Asked by Pete 9 years ago
Add your answer
Verified Reply- SupplyHouse StaffIt comes preset to 50psi, but it depends on what you want at your fixtures. You can set between 25 and 75 psi.
Q: what is the overall length of this unit

Verified Reply- SupplyHouse Staff0009353 is 10-3/4" end to end.
Q: does this unit have a relief bypass?
Asked by bill 10 years ago
Add your answer
Yes, the standard bypass feature permits the flow of water back through the valve into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main supply.
Q: If the pressure on the exit side exceeds the pressure on the inlet side will the flow be reversed. i.e. Will this valve allow a backflow to occur?
Asked by Har 11 years ago
Add your answer
Verified Reply- SupplyHouse StaffYes, from the product literature, "The standard bypass feature permits the flow of water back through the valve into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main supply."
Q: What is the maximum flow rate if I reduce the outlet pressure to 50 psi?
Asked by marc249 11 years ago
Add your answer
That depends on your input pressure. At 75psi input pressure, a 2 inch reducing valve is spec'd at 95 gpm. However, it tails off quickly. At 65 psi input, you are looking at only 45 gpm. If you need more, I would recommend you look at the U5B series where at 65 psi input you would get 85 gpm. There is a big difference in these valves and I always recommend the U5B series over the 25AUB series for just about any application.
Q: I have a Watts value now and I want to make sure this one is the same lenth. How long is the vale from end to end. Thanks

Q: does this valve have a thermal by-pass
Asked by sam 11 years ago
Add your answer
Yes. The standard bypass feature permits the flow of water back through the valve into the main when the pressure exceeds the main supply due to thermal expansion on the outlet side of the valve.
