    3 of 5 stars  Questioning manufacturing?
    By Bk in Sausalito, Ca on 07/02/2010
    Verified Purchase

    This container got the job done...and I had my hand in it's use, plus my handyman's help in setting this up. However, my handyman questioned the longevity of this product. The manufacturing of this pump sprayer disappointed him. Running a comparison with this sprayer and one he had from home depot, which cost $5.00 more: he wanted the handle of this pump to not leak air after the first use. The seal around the opening and the threading hissed air. The black tubing from the container bent and pinched off easily, in his opinion: he wanted to see a more pliable tubing. The "fan spray" did not spray in a fan configuration.

    5 of 5 stars  application is a breeze
    By Kimberly in Indianapolis, Indiana on 08/14/2010
    Verified Purchase

    The pump sprayer makes application so easy. My husband didn't want me to purchase it with our last order and said he could find something else to use that would be cheaper. I ordered it anyway, he used it and realized it was perfect especially for the price. He had looked around and found nothing that compared to the value, durability; and the others couldn't guarantee sprayers durability with the use of chemicals. You won't be disappointed especially for the price, excellent value.

    By Brian in Kingsland, TX on 07/07/2010

    I really like the idea that this sprayer has a nice full fan pattern. It really does a great job of applying the home barrier. Also, it pumps out every drop w/o leaving a residue in the tank. I've sprayed both our home and our daughter's place.

    4 of 5 stars  Relatively cheap, but effective
    By Brian in Easley, SC on 06/02/2016

    Seems decent for the price, I bought it since it was sold with the chemicals being purchased, but a big box store in town had it at a similar or lesser price as well I believe. No pressure relief valve, so be aware. I just spray the remainder until it dies before opening. Don't open until you've drained pressure by spraying or emptied the contents unless you want to wear the contents. No problems with operation, has a decent fan mode for spraying general pesticide.

QCan you use Chapin 1 Gallon Pump Sprayer (#20000) with the Demon WP?

AYes. Demon WP can be used in the Chapin 1 Gallon Pump Sprayer (#20000). We recommend filling the sprayer with 1/2 gallon of warm water, add the Demon WP and let it sit in the water for about 5 minutes. Stir/agitate the mixture, then add the remaining water and agitate mixture again. It is important to remember that Demon WP will not truly dissolve into the water so the mixture will need to be agitated frequently to avoid clogging your sprayer.

QDoes the Chapin pump sprayer (20000) sprayer have a high pressure relief valve?
I was looking at the sprayers that you have to offer so I could compare them to see which one would be perfect for the task I need to do, and I noticed that it did not mention anything about having a high pressure auto/manual relief valve.

ANo, the basic Chapin sprayer #20000 does not have a pressure relief valve.  Only the Premier sprayers, models #21200 and #21210 come with a pressure relief valve.

QChapin wand flexible?
I have cabinets that have a void between the bottom and the floor. There is a kick plate and I usually bend the wand a bit to get it over the top of the kick plate and treat the void. A stiff metal wand won't work.

AThe wand on the Chapin 1 Gallon Pump Sprayer is plastic and not metal. We cannot guarantee that while the wand is plastic, that is would be flexible enough and would not break.

QMultiple chemicals
Can one sprayer be used for several chemicals? Example: Talstar, Demon Max, and Termidor SC?

QUse Chapin 1 Gallon Pump Sprayer for both herbicide and pesticide
Can I use this sprayer with weed and grass killer and then use it with pesticides on my plants? I can clean it out between uses that I did not know if it might absorb some of the product. Please advise. Thank you.

AChapin 1 Gallon Pump Sprayer and with any other sprayer we recommend using different sprayers when applying an insecticides versus herbicide. There is too much potential of residue left behind.

I will be applying an acid concrete stain to my patio. Will this sprayer handle it? Recommendation is not to have any metal parts in the sprayer.

QDoes this sprayer allow for a fan mist or is the fan mode more of a no pressure sprinkle?
I need this to spray a light mist to cover ceilings and walls with The Demon WP product for roach control. Thank you!

AThe Chapin one gallon sprayer will give an actual broad mist when the nozzle is in that position. However, please note that no spray should ever be used as a broadcast spray on ceilings and walls or over your head for safety reasons, and Demon is specifically designed for baseboard and crack and crevice treatments only. You not only would be using the product against the label instructions, but you risk having the spray come back on yourself or other areas of the room that you wouldn't want the product to be on. A better application for roaches in high areas would be a bait gel. You can find the proper techniques for treating all areas of a home or business for roaches in our article here: How to Get Rid of Roaches.

QI just received my shipment of rodenticide for chipmunks.
How long does it remain potent? I have a dog on a leash currently because of leg surgery, but the dog will eventually have the run of the back yard again in 2 months. Actually, the label of this rodenticide scares me. Will the dog be safe?

ARodenticides are safe to use around pets as long as you use them correctly.  Bait can remain potent for a long time, sometimes up to a year.  This is why you should place the bait in tamper resistant bait stations, which let the rodents and chipmunks in the station and keeps the bait secure, but will not let your dog get to the bait.  You definitely do not want to let the dog roam around the yard with rodent bait sitting out.
