Replace 0-ring I have an older green thumb 2 gallon sprayer made by gilmour. hate to replace. o-ring on pump head has broken, tried to have one made without success. (349 115/201GT) o-ring was odd diameter but approximately 3". please be in touch as I would like to be able to replace this ring so the sprayer continues to work. thank you jeff rice [email protected]

clean the blockage from the nozzle
replace the "O" ring on the pump shaft

Got the same sprayer, can't get parts. Toss it in the trash like I did, don't buy anymore Gilmour products.

Hello,
If you see water leaking it might be that the plastic has a broken, try to seal it with super crazy glue.
Thanks

Generally, the problem is either a leak or a bad pump. If you listen carefully and you hear air escaping try making sure the top is on tight (don't go nuts because you will never get it off again) Also many tanks have a gasket or O-ring under the lid. This is often lost or gets out of place, and then crushed by the lip. There is also a gasket or stopper thing at the bottom of the pump cylinder, sometimes this gets loose or gets a piece of stuff in it. It also could be the pump piston itself. HERE is the manual with a section on troubleshooting.
Be careful if you have used hazardous chemicals in it before.
Hope this helps, If it does please rate it.

Your pump cam follower may be broken, such that the pump is just not working. Good news, you don't need to buy any new parts. If you open it up and find that the cam follower plastic tabs are broken, Gilmour provides a second set of 2 cam followers on the other side of the cam follower assembly. Just remove some screws, reverse the assembly, and you are back in business. Since the higher the wheel speed the more stress there is on these tabs, I would not recommend moving the wheels any faster than what occurs with a slow walk.

hi
these hi pressure hose are not repairable / new one needed

You add oil in the two holes to lubricate the seals around the pump shaft. Maybe the seals have dried up now and that is why the air leaks by.

Im pretty sure that is all it is. The pressure is by how many times you pump it up. Its just on or off. Sounds like It needs to be cleaned real good, and put soap in it befor you put it bak together. Also there is a screen if you hold the handle and turn the trigger part and unscrew it.
