SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

by "floor", i referred to a concrete slab that sits under the pumps (pool and sprinkler). With only 14 inches of room, I will have to install the filter at an angle. I have Vu Flow's number to call them to ask if an angled installation will be ok.

I am afraid that "slight" angle may end up being in the 45 degree range.

Vu Flow told me it should be ok as long as I dont point it upward. Duh.

I did not receive an e-mail.

You mentioned "floor" which makes me presume your pump is indoors? I would definitely install these items outdoors. The relief valve, if ever activated, will expel massive amts. of water. The filter can be installed indoors if absolutely necessary, but best if outdoors.

I would go with the 2" filter, for the simple reason of more time between cleanings. You would need reducer bushings to go from 1.5" to the 2" filter. Installing at a slight angle is fine.


Adjustable Pressure Relief Valve

Hey central

sorry to bug about this again.

After much online searching for the filter an dseeing the same prices (more or less), I came across one at my local Home Depot for a lot less. Amazing.

I will be installing it very soon, but I am afraid of cutting that pipe. It is easy to install pipe when things arent glued and connected. On one end of this pipe is the pump, on the other end is the zone valve with 4 pipes heading into the ground. So I have little room to push and flex in either direction to make a tight fit once I cut. I've searched for youtube videos and others to learn how to do this, but it is an important cut that I want to do properly.

I see that the zone valve has a screw connector that I can probably unscrew so that I can cut, glue, and make sure all fits correctly. I will leave that as a last option. However, since I have to put in the pressure relief valve, the filter, and another ball valve, I might as well unscrew that screw conncetor from that end and rework.



Any suggestions from you?

Thank you

perhaps I am. I complicate things sometimes, but I just want to do this right, that is all.


Also--what about pressure loss? On the back of the box is a graph basically showing that as flow rate in gpm goes up, so does psi loss. But I dont know my gpm, and either way, the loss is guaranteed (according to the graph).

i wasnt concerned about orienting it, I am concerned as to how to cut the existing pipe to add the strainer, and to do so correctly so that it is glued snug and tight. SInce I want to add 3 things: pressure valve, strainer, and another ball valve, I might as well cut after the existing valve, and replace the rest.



the mesh is 60.

Quoted from "Wet_Boots"

If you want the best performance, you take it down to the pump itself, and start over. Save nothing on the outlet side. A 60-mesh screen may not protect the zone valves. Better is 100 mesh.

thank you Boots

I am sorry, but I didnt understand your reply. Are you telling me to get a different pump? Or to remove my existing pipe down to the pipe (on the outlet side), and start over?
