If you would like to FRY your 12 volt pump, please do the following:

1.  Use a 1/2" id chemical hose or smaller instead of 5/8" or 3/4".
2.  Use a 1/2" clear braid poly hose on the suction side of the pump instead of 3/4" or 1" ag hose
3.  Use a mushroom type stainless steel filter in your chemical tank and watch it fall apart and get sucked into your pump instead of a slotted tank filter composed of pvc.
4.  Place your pump in a hot little black box and don't drill any holes in the box.  (If you are lucky, you will reach that seredipitous moment of watching a pin prick size hole allow chemical to fill the box and drown your pump.  You will know that the pump can not be resusitated when the factory installed smoke gently rises from the tomb)
5.  Plumb in a few or more 90 degree fittings
6.  Use hose barbs and hose clamps that will allow either leaks or air to get into the system.  Keep some bandaids in the truck and keep current on your tetanus for slices due to the rusty hose clamps
7.  Use nozzles that are smaller than 30 orifice
8.  If using a Fatboy, use a poly gun and wand to restrict your flow instead of a 3/4" ball valve and reducing bushing.  (Thanks Mike Sullivan)
9.  Don't rinse your pump.  Allow it to simmer in the Love.
10.  Think small and think restriction.
11.  Use poly fittings.  They will crack without notice.


Listen for an unusual grinding sound and the off and on of the pump which is called cycling. 

Pressure Washer Products enjoys seeing our RCIA customers receiving tremendous returns on their investments.  When plumbed properly, these pumps will last and pressure switches do not have to be replaced.  For $115 or $215, these pump will put food on your table.

For the best return on investment, do the OPPOSITE of the above mentioned list!

Someone needs to come give my Fatboy a good scolding for not frying itself. How dare it go against Mike Sullivan and PWP!

Here is one of the flow loss threads posted by Tim Asleton. It is important to realize these loss demonstrations were done with a 2 gpm shurflo. Small hose effects a small gpm pump less, loss gets even worse at 5 to 7 gpm, as you have on the delavan fat boy roof cleaning
pump.

Here is another roof cleaning hose diameter thread with a flow loss calculator in it.


Now Scott, roof cleaners are free to use what they want, and if you want to deceive yourself into thinking that 1/2 inch hose is "as good" as 3/4 or 5/8, thats your business. It is not, as has been proven over and over again by myself, Tim Aselton Softwashing Tallahassee FL, Mike Sullivan, and several other roof cleaners before your time you never heard of, including Larry Hinckley from Delco. Understand, we are not attacking you personally Scott, because speaking for me, I like you
But this is the RCIA Forum, people come here for the very best roof cleaning information, and we try to provide it. When one of our certified roof cleaners posts information like this, it confuses people. So, can you provide any scientific evidence to prove 1/2 inch hose is "just as good" as 5/8 or 3/4 ? have you ever done flow and pressure loss calculations to back up your claims. Or, are you observations based on the roofs you have cleaned ? Remember Scott, people used to wash clothes on rocks in a stream, and re stock their ice boxes before they had washing machines and refrigerators ? Just because their old ways "worked" dont mean they were better, or even as good. We think people come to RCIA to be the very best they can be at roof cleaning, and not just be "good enough".
If they want to be just 'good enough", there are plenty of "me too" Cleaning Forums where roof cleaning information is an afterthought. I guess when some play pool for money in a bar, they pick up whatever pool cue they can find ? Me, I bring my own custom made pool cue stick. Some fish with cheap Wal Mart rods and reels, I use Penn and Shimano tackle. Many of my tools are Snap On, some use the 29 dollar tool boxes from an auto parts store. Some like round steak, I like Porterhouse. My false teeth stay in better eating good steak, LOL

Scott, many here at RCIA pay extra money for 28 inch Titan reels to hold the big hose we use, are you saying we are crazy ? We do it because it is better to use bigger hose diameters on any pump. remember, the pump is working against friction loss Scott. The less flow and pressure restriction, the easier the pump has it. Why make your pumps life harder ?  I will see if I can find the thread where Tim Aselton did actual flow and pressure loss demonstrations on different hose sizes, and if not I will post an online flow and pressure loss calculator to show you how much you are giving away by using smaller hose.  The more flow we have, the less strong our solution has to be, since we can flood a roof faster and better, assuming run off is not excessive. I will go as far as to say this Scott, and this is not personal buddy. Any roof you can clean with a delavan and 1/2 inch hose, an equal to you roof cleaner  can clean faster with 5/8 or 3/4 hose, and his pump will last longer too. He will be able to spray farther and
faster. Hate to say it my friend, but with bigger hose, he will put a roof cleaning azz whipping on you

Lori,

What is a slotted pvc filter? Is it the pvc that has the white cap on it, with 2 holes in the bottom of the cap?

If so, how does the Love flow thru those small two holes? Will this not put strain on the pump trying to pull the Love thru?

Maybe I am missing something here.

Why would vendors sell you the 5850 roof kits and provide most of the things you say's " FRY'S The Pump"? i,e stainless steel mushroom filters, 1/2 in hoses, hose clamps, LIL black boxes, Poly guns 'etc.

All the things I purchased to start my roof cleaning Biz. I will start modifying some things.

We prefer that our customers do not have pump problems or that the life span of the pump is as long as expected or greater.

We are finding success in upsizing the hose on suction and discharge. Chris T and Mike Sullivan have everything to do with this information. Our records on phone calls for tech help for pumps purchased from the 'other' vendors prove it also.

When you use the correct size hoses and nozzles you do not burn through pumps and pressure switches. I have many pressure switches laying around becuase Delavan told me to make sure that I had them. We rarely sell them.....because of Mike and Chris' advice.

Not a personal issue....it is a pump issue!

 Yea, I figured you wouldn't name any names. It seasier to take pot shots that way. Its wierd, because the "other" suplier offers a warranty on the pumps just in case, so how would it be beneficial to sell them in "lil black boxes" or with "restricting" hoses if he would have to replace the pump for free?

Please tell me you have other sources other than Chris T and Mike S. Im not saying they are a bad source, but please tell me your knowledge of roof cleaning and the equipment extends beyond 2 people on this board.

Lori, if you are going to accuse, please dont be vague. Im not vague in my accusations and niether is anyone else. Please man up.
