Average Reviews:
(More customer reviews)This diaphragm model of the Solo 475 sprayer works well as a sprayer.However it is extremely difficult and maybe impossible to take apart for maintenance.I went to the local dealer that Solo lists as providing repair services in my community.I asked him if they do maintenance and repairs and he said they don't because they are too difficult to work on.I decided to take it apart myself and do the maintenance.So far I have been unable to remove the pressure cylinder from the unit.I went to Solo's website and downloaded all of their maintenance literature and I watched the maintenance video at their website.
The video shows the maintenance person using a one foot long 2X4 and a heavy hammer (they say use a HEAVY hammer)to pound the pressure cylinder cylinder out.I have used a small sledge hammer and still have been unable to remove the cylinder.
I had hoped the "repair shop" listed by Solo would know what to do.They say, no they are just hard to work on.SP Systems also makes a diaphragm style backpack sprayer (sold on Amazon).I would try that brand instead.It couldn't be worse to maintain than this Solo (since it may be impossible to maintain.)
