Jets clogging too much! Remedy?

[Hack Attack]

Possumbly.

what did my head in is the realtor knew? He'd kicked the tenants out months ago for being ferals and wanted it "just tidied" to sell

Are you using hard water? The higher the heat the more scale separates from the water. If both of these are true then it could be scale. Notice there are some hard water areas in Michigan from the map in the article. I tried to copy the map without success.

Thanks for chiming in, Tom. I don't use hard water--just softened 6.5 about pH as a clear water rinse after our normal preconditioning with detergent, usually Saiger Sauce.

I think we have our problem solved. We replace the 4 ft hose just before the manifolds on the wands and the Parker Parflex is performing beautifly. No clogs all day! Yahoo!!!!!
