Orbit 2- Pack Adjustable Flow 8-Port Drip Irrigation Manifold for 1/4" Tube - 61008P

1/4" pipe, softened with a lighter for 1-2 seconds, easily push onto the nipples.Without doing that I managed to buckle couple of themI did not fit any dripper at the other end of the 1/4 lines- just used the adjusters.VERY useful as plants grow to increase their supply.Flat bladed screwdriver easily slips on adjusters. Some users suggested a small square headed bit,Not sure the "hole" in the center of the adjuster is anything more than just that.So perhaps I shall grind down an old flat-bladed screwdriver to leave a projection in the middle of the blade toprevent it slipping. I can see how slippage and over-torquing would wreck the thing eventually.Also I found it hard to get adapters to go from 1/2" irrigation push- or screw-fit to the 1/2" NPSfemale socket under this thing.Otherwise-- PERFECT for my Veg. garden where lots of plants are close together,And-- Good Value. PS-- Don't forgot to regulate Pressure in your system : )

Pro:+super easy to install+comes with 8 ports with caps on each of them for the ones you don't use+each of the 8 ports has it's own flow adjustment screw+this unit with 8 ports was cheaper than units with less ports+flexibility in use, you can use just 1 or all 8 without any noticeable pressure drops+if there ever is you can adjust them to compensate for any pressure needsCon-requires you also purchase "Rain Bird RCKIT-1PS Connection Riser Kit, Universal" which is nearly the same cost as this unit around $17 to $20-it's plastic so it's easy to break so be careful during installation of drip lines and while turning the adjustment screws.We replaced random spray heads with these and ran drip lines to each plant and it is wonderful. Watering can be tweaked to the needs of each individual plant without watering the sidewalk, the house, the neighbors cat. Perfect water distribution.Now if I could only remember which screw went to which plant so it would be easier when I see a line giving too much water I have to adjust each one till I find the right one, but that's on me and my horrible working memory. If I only wrote things down or put labels this would not be an issue.Closing thoughts, great product with superior flexibility in use than other similar products perfect for fine tuning your watering system and saving money in the long run by not wasting water on areas that don't need water. Too much water going everywhere can help weeds grow.In our yard with random spray heads anywhere that wasn't plants or grass that got overspray grew a ton of weeds, the areas that never got overspray never grew any weeds. It was then that I knew I made the right choice and will be upgrading all other spray heads for my garden to this drip system.I didn't feel the need to upload a photo as it is what it is, product is exactly as pictured in the amazon page.

Two very important things to know about these delicate gizmos. 1st, don’t screw them on to an nip tapered pipe, pvc included. They are meant for an untapered stand and will easily crack otherwise. 2nd, the center fitting on the top is a pressure valve. You must adjust it first before you try to adjust each individual nozzle.

I have purchased and installed 4 of these in the past few weeks. They are easy to install. With a firm 1/4" drip line you simple slip them over the port. If you are using a softer drip line use small zip ties to secure them. Each port is individually adjustable, making easy to mix drip and sprinklers on the same manifold.

Quick delivery. Work as advertised.
