A great sprinkler for large areasNovember 6, 2004 Robert F. Heller Jr.(Winter Springs FL) 1 out of 1 found this review helpful
This is the only sprinkler I have found that is adequate for my front lawn. It covers about 100 foot diameter with enough water flow so I don't have to water for hours on end.
Before purchasing this sprinkler, make sure you have a good water source and are using the proper hoses. The instructions say to use maximum hose length of 100 foot of 5/8". I am using two Apex commercial-quality 5/8" 75 foot hoses (150 foot total)with metal fittings and my pump has a feed pressure of 48 psi when running the sprinkler. Works great! If you have low water pressure or inadequate hose then buy a lower-capacity sprinkler.
Problem With Gilmour 998FBAugust 17, 2004 hardhead We have two Gilmour sprinklers, 998FB and 998ZS. Both have the same problem. They get stuck at one end of the range of coverage if water pressure is not at its peak. If you do not have consistently high pressure you might want to try another model.
