Mike if you wo uld just tell me what size hose and airflow pump to buy I would appreciate it thanks again

Starting out I would get a 12V Delavan pump.

If you are serious about full time roof cleaning, then get the 3/8" All-Flo pump Dave suggests on the Roof Cleaning Pumps thread with 200 ft. 5/8" Kuritec 200psi hose.

Clyde i agree with Bill on this one get the all flo pump an take the time to set it up and you will not be sorry.The total price difference is not that much.You mention you clean already you will be amazed when you get on a big deck or a big area of concrete covered in mold,just point and shoot in minutes the spraying will be done with the 3/8 inch all-flo.I went with the all-flo,air compressor set up and its great.No wires to rig up,no batteries to keep charged etc.Good luck with it either way you go.Call and talk to Lori s Dad  he will have you ready in about 10 minutes.

Thanks Hal

Can I ask you what solution you use to clean concrete that is covered with mold, mildew and dirt?

 

Hal what are or is caustic beads?

You want 8cfm minimum 16 cfm optimal from you air compressor. A torpedo will do fine as long as it is at least 8cfm. Search for the Air diaphragm posts. Cfm are the key to success. Also the bigger the air tank the better.

Over 100 roofs this season and no rinsing!! no jamming!!! no leaking!! No problems!! High flow rates that do not variate!! The All flo brand pumps are offset meaning they do not stall in dead head mode. My kvm-038 has never stalled once. The yammadahs have a reset button for when they stall and the versamatics stall every time and have to be disconnected/reconnected from the air to un-stall them.

Kynar FTW!!! Stay away from the poly pumps and remember there ARE NO KYNAR ELECTRIC PUMPS AVAILABLE. so they will fail every time from repeated use and NEED to be rinsed to survive. 

AODD pumps dead head out when you close the valve compared to an electric that needs to be bypassed, shut off or just fries under load from being dead headed. 

Bypasses fail and cause foam!!

It is true that electrics will get you by for a time, but the facts are simple....If you want ALL A rated materials against SH you can not find it in an electric pump.

Clearly stated!  You and Hal are absolutely right!  Thanks guys!  Lori

 

Great question! The KVM has the max-pass. All-Flo says it will only last half as long.
