(5 Pack) Rainbird 1804 Series Pop-Up Spray Head with Seal-A-Matic and Pressure Regulator Without Nozzle, 4"

These performed perfectly. We had continual drippage/leaking of some heads on the downward slope of our front yard. Installed these PRS and the drippage ceased. It actually pushed the leakage upstream so that other heads began to leak, so we replaced those as well which resolved the problem. Well worth the money.

I bought 10 of these, and they do NOT have the Seal-a-Matic feature which presents all the water in the zone from running out of the lowest head after it's turned off. Typically, heads with these features will say SAM-PRS on the top. These are not labeled as such, and I can tell by inspecting them they do not have SAM.

These sprinkler heads along with high efficiency nozzles are the way to go. Check valves and pressure regulating sprinkler heads are required by the city where I live.Don't waste your money on anything else.

Had some chronic leaking from several heads in one zone w no evidence of valve leakage. Put these on and have been leak free since, so I’m pretty satisfied

It is not specified in amazon but the ones I received have an optimal pressure of 30 psi (1804 - SAM - PRS - P30) . If you are looking for optimal pressure of 45 psi (1804 - SAM - PRS - P45), these will not do it. The seller should specify this information.

Exactly what I needed & much cheaper than Rainbird online. If you are looking for the 45 PSI version, this is not it (this model is 30 PSI). Rainbird calls the 45 PSI model 1804P45.

These sprinkler heads are described as being Pressure Regulating and they clearly are not! Installed one and the water was running out after installing it. Do Not Buy these.

Not as advertised, tried these products twice, both times they come as standard 1804 bodies with no SAM, seal-a-matic, and no PRS pressure regulation. Do not buy if you want these features.

Il faut les acheter à part en fonction des surfaces par buse, de la pression, etc etc. Sinon bon produit à prix très correct par rapport à la concurrence. Livraison plus rapide que annoncé
