Our 
					tanks that are used to support pressure washing applications 
					are made from very rugged high density polyethylene. You can 
					select tanks that have pre-installed fittings or if you need 
					something special, you can select 'blank' tanks that can 
					have fittings installed to suit your particular needs. Other 
					shapes of tanks will work for Pressure Washer applications 
					but most people select the Horizontal Leg Tanks.
