Rain Bird RBY100S Drip Irrigation In-Line "Y" Filter, 1" x 1" Male Thread

I noticed right away that this product is going to work well in my somewhat complicated drip irrigation system. I running this filter in the actual garden hose (I cut the hose and bought some barb fittings to make it an inline filter prior to my drip system). After the filter the water goes through a pipe where I branch off to a spigot for a hose on my deck and then up to another spigot that runs a Y with two water timers that go off on opposite schedules as to keep good pressure. The system works like a charm, however, I have to watch the fall for freezing temps and I blow out the lines with an air compressor and remove the plastic water timers to prevent bursting. Here's a cool trick, use half inch drip line that then tee off to soaker hoses with a valve at the end of each one for easy clean out each year. This save money on all those expensive drip irrigation drippers that can clog but it takes a bit of work to find proper fittings, hose clamps, and I use a touch of 100 percent silicon in each fitting to insure no leaks....anyway, it works for me and was a lot cheaper than a full drip system. You can replace the soaker hoses every 3 to 6 years if you like yet I've run mine for 4 years with only a leak now and again that I use a fitting on to fix.

Just what I needed for pressure reducing drip lines.

This filter / pressure regulator is just perfect for drip systems. Most installations put a filter behind the valve. Many of these are made of polypropylene and are not rated for supply side pressure. Here's a trick not commonly shared. Put this filter / regulator behind a shutoff valve for servicing, then install your valves and install your drip systems. Guess what? you now are protecting not only your drip lines with a 200 micron filter and taking the pressure down to 30 #s , but your protecting your valves, all with one filter. This unit is rated for 150 #s, so unless you have really high pressure on your supply side, this will do the trick.This is available in a 1 inch size with 40 lb. regulation. If you install this model on a 3/4 in. line, you will just need two reducing adapters. I would also add a union, yes they are made in PVC, to make removal / installation easier.

It works great. I probably should have done a bit more thinking before installing it, and put it before the anti-siphon valve, instead of immediately after. It would probably extend the life of the valve, which is a $50 solar powered timer type.

I used this step-down in-line valve to reduce the PSI (down to 30 PSI) on a new zone I created off my 3/4” irrigation system which I specifically designed (with 1/2” black tubing, 1/4” spaghetti lines and drip emitters) to water flowering pots in our courtyard that get full sun. This summer has been brutally hot; so I also created a Program B off my Rain Bird controller that waters the pots, not once, but twice each day for short periods. I’ll have to adjust that as we get into the fall, but I’m very pleased with the result.I should add I’ve used these valves on two other zones… the spray type sprinkler heads were keeping the bottom halves of our shutters wet and they were rotting well before their time. I stepped-down the zones replaced the sprinkler heads and installed drip tubing (brown tubing with small holes every 12”) and am very pleased with that as well.

Arrived on time - well packaged - worked great - used on my Drip Irrigation system - having the pressure reducer installed with the filter makes installation easier

Very strong, easy to install, and very convenient to clean out

I installed this regulator in March. So far the irrigation system is consistently using the same amount of water on each cycle. I haven't tried the cleanout feature yet but I will this fall.
