It was good for a few weeks but it the wand split where it curved
Thank you for your comments! Proper cleaning and storage is important when using brass equipment, especially. You should be sure your sprayer is clean and dry when stored. If the wand is exposed to excess pressure or freezing or strongly fluctuating temperatures, then the wand may crack or break.You can sometimes secure the wand with tape and still use it. Please let us know if you have any further questions or concerns.
Will the Chapin 12 inch extension(part 6-7701) fit the 21210XP?
Yes, the chapin 12 inch brass extension wand will fit the Chapin Premier 21210XP as well as most other sprayers that have brass handles, wands and nozzles. Chapin's rule of thumb for their sprayers and parts is brass to brass, plastic to plastic. You can use this extension by itself as the actual length of your wand, or attach it to the end of the existing wand for extended length.
The extension can be added to the existing wand, don't both wands have a 45 angle on them?
How would this work?
The Chapin sprayers come with a wand with a slight bend on the end, however when purchasing extensions to give you a longer reach, you can get an extension that is straight to add on like this Chapin straight 24" wand.
