This will allow people to understand what your looking for, and what your area of expertise is.
The owners and moderators of this forum have repeatedly stated that they like people asking questions. Unfortunately, sometimes people fly into this forum expecting immediate and concise answers to their questions, as if the members have some obligation to do that. Let me say that I only know what I know about PW because the members on here helped me out. They will help you out too, just give them a second. Sit back, if you have time to drink some coffee or tea then peruse a few threads about nozzle sizes and 12v systems while drinking it.
