We have a Toro ( ithink?) pw from the depot,cost about $300...nothing fancy, 2800 psi or so, 3gpm I can never seem to get the soap intake hose to work properly....any idea what could cause this? It worked for about 5 operating hours and nothing since we only do small projects as an add on...maybe 2-3 homes each season...but i;d like to get this thing working! the filter screen isnt clogged...beyond that im lost!! Also, i keep reading about this simple cherry product...is it available locally or do u have to order? is anything found at the home depot effective???
