Roundup 181538 Sprayer Parts Repair Kit

This kit worked perfectly to rebuild my 2.5 gallon Ortho sprayer. Works like new again!

I have two Roundup sprayers, both the large 2 gallon type. I use one with Roundup to kill the weeds all the way around the house, when they push their way up through the rocks. The Roundup does a great job. In the other Roundup sprayer I have weed killer for lawns, which also does a great job in the Roundup sprayer. Yesterday I discovered one of the Roundup sprayers let in air every time I pumped it. It was so frustrating, I couldn't use it. Today I went to Home Depot to look at the sprayers. I told the sales person who was helping me, about the problem with the sprayer. He showed me this kit. I was a bit reluctant to purchase it, as I wasn't confident that any of the washers would fix the problem. I asked the man if it didn't work, could I bring it back for a refund, he said yes. When I got home, I took the old washer off, and compaired it to the washers in the kit. Clearly it was the largest one I needed. I followed the insructions, by smearing vasaline on it and then stretched it onto where it belonged. It was a nice and tight fit. I pumped the plunger a few times, I couldn't hear any air going in. When I tried spraying, it worked. I felt very pleased with myself. I'm glad I got this kit, it saved me some money, I was all set to buy a new sprayer. The same kit cost almost $7 without tax in Home Depot, it costs $8.86 here with free shipping. I probably paid almost the same here, by the time the tax was added on at Home Depot. I'm very happy with my purchase. I may buy a spare just incase the other sprayer needs fixing. I'm adding this to my wish list. **UPDATE** It's been over a year since I reviewed this product, it's still working great. Recently I discovered Home Depot didn't have these any more, so I purchased a spare from Amazon, so I have one handy. Very happy I can get them here.

I purchased 2 of these Round Up 1 gallon hand pump sprayer repair kits. The one way check valve on the bottom of the hand pump is an exact fit and seals the bottom of the hand pump by preventing air and liquid from entering the hand pump . The smaller of the 2 O-rings that fits near the bottom of the actual pump handle is an exact fit. It doesn’t allow air and liquid to escape into the hand pump itself. The smaller rubber gasket that fits on the outside of the Hand Pump. That seals the hand pump to the 1 gallon tank Is an exact fit. No air escapes and seals the hand pump to the 1 gallon container perfectly. First I took apart the hand pump. The instructions to do so for a Round Up hand pump sprayer are printed on the back of the repair kit. Then I cleaned the inside and outside of the hand pump and the 1 gallon tank with dish soap and a bottle brush using hot water from my kitchen faucet. I dried the inside of the hand pump using 2 paper towels. Then I applied some silicone grease to the top edge on the inside of the hand pump. I applied a small amount of silicone grease to the O-ring,one way check valve and to the gray rubber seal. I picked both of the 1 gallon Round Up hand pump sprayers out of the trash. All both of them needed was the Round Up Hand Pump Sprayer repair kits. By Picking the sprayers out of the trash. It Prevented them from going to the landfill. The kit even comes with an adjustable sprayer for the end of spray wand. The cost of the repair kits are very reasonable. My old hand pump sprayer has a stainless steel tank and it started leaking. I did weld the area it was leaking with stainless steel welding rod. Now I’ve 3 hand pump sprayers. Allowing me to use each individual sprayer for cleaners, insecticides and Round Up weed killer. I only use round up when absolutely necessary and only enough for the job.

This is an easy install. Factory spec. Fast ship. Good product. Wil buy again.
