I am using 1/4 inch coiled foaming brush hose from
kleen-rite. The swivel on one them is leaking, so I was going try a previous suggestion and get a 3/8 hose to try on that bay. I think Earl suggested trying that. I don't know how old the handles are. I didn't replace the handles because they looked good. I'll get a new handle and fittings along with the hose. The fitting were corroded when I took the handles apart and cleaned them. I was reading back through the thread and based upon one suggestion I'm wondering if I need any foaming material at all. Right now the material is in the brush handle.
Thanks
Mike
