Will this work for a 22ft trailer

For regulating. City water pressure to trailer
Asked by: Tasha
No, this regulator is not for main line installations where it will be under continuous pressure. You need to use a brass, adjustable direct acting adjustable regulator or the DIG PRV075.

I have one pressure regulator marked PD8325. Is this the right model to connect a hose bib with a Gardena timer

Pressure Protecfion with No Flow

Do DIG pressure regulators need water flow to regulate the pressure? Went there is no flow inthe system, will the pressure rise back up to match the input pressure? Also is there a maxiumum input pressure?

Product may works for some period of time (months; 3-24), but ultimately fails, depending on usage and line pressure. I am having to replace several with the DIG 30 PSI regulator. Unless money is dear, it is not worth it.

Rated 1 out of 5 by from Really Bad Design I have tried many of these in my drip system, most have failed. I have replace several only to have them fail again. The problem is the design of the regulator piston which is simply a molded plastic tapered seal. The piston seal fails and water leaks past to the vent hole on the side and then it floods everything. I would think Home Depot would evaluate the products that they sell a little better. I am going to have to find something else to work in its place or replace the entire system.

Rated 1 out of 5 by from Short Life, Leaks I replace this reducer every 6 to 10 months for leaking. I put a union in the pipe for a quick replace. I'd rather pay more for one that works and doesn't leak. Going to search more. Do the HD purchasing agents ever read the reviews on the products they buy for the stores, or are they ok with customers being unhappy and going elsewhere?

Rated 2 out of 5 by from Fail Far Too Often I have a fairly large drip system, using 8 or 10 pressure-reducing valves. I started out using these, since they are convenient and inexpensive. They work for a while, but fail far too soon: within weeks to months. Might be because my water pressure is over 100 PSI, but they seem to get calcium deposits quickly as well. I'm going to try the more robust Model # PR-30-PIPE, rated for input pressure to 150 PSI, and at over twice the price, but if they last, money well spent.

Rated 1 out of 5 by from Junk pressure regulator Thought I would give these one more try, have had problems in the past. This one lasted less than 2 weeks before it started leaking out of the hole on the side. Really disappointed that HD would continue to stock and sell a product that is such a piece of junk. Will have to see if I can source something more predictable somewhere else.

Rated 4 out of 5 by from For connecting from your sprinkler system to your drip system 25psi, 3/4" Female PIPE Threaded x 3/4" Male PIPE Threaded: I've determined that this plastic drip system water max pressure regulator is just like the black "PD-8325" regulator (25psi) except this gray "PD-8425" has finer threads (more threads per inch) to connect between your sprinkler manifold and your drip system piping. Suppose to keep the water pressure under 26psi for the low pressure drip system (or micro sprinklers or soaker hose). You don't want the drip system's tiny parts popping off due to high pressure. These are fairly solid, not thin walled like some I've seen, and shorter/more compact than other regulators I've seen. Don't over tighten, since the ring does the sealing, it's not necessary, and the plastic threads could strip.

Rated 2 out of 5 by from Piece of "stuff" Failed after about a year. Water now jetting from the port on the side. Fortunately port was pointed up so the water all came down and softened up the soil so I could dig up the pipe it's on easily.
