TROPO and all everyone else,

As we do not know your EXACT budget and entire pump setup, here is some more examples for hose and other reference info for you and alll, to consider.

BELOW is the link for Kuri Tec in 1/2" Yellow. This takes you directly to the page for your review.

It is  1/2" and does not flow quite as well as 5/8" but still applies plenty of chem to the roof with an electric diaphragm at 3-7gpm.

Larger pumps in the 8-15gpm will require 5/8" to flow and work at their best performance and capacity.

I have 1/2" Orange (not yellow) and use it on one of my rigs on three reels of 250ft. on each TITAN reel which I purchased at (Pressure Washer Products.com speak to Lori for the BEST price) and I like the hose very much over the clear 5/8" nylon braided Kuri Tec which is more pliable but is food and beverage grade with nylon crosshatched braiding which is less resistant to developing blisters and blowouts as the chemical works against the material over time.

I also use 5/8" on another rig with a larger pump and the flow is almost overwheming at times but is great for large roofs. 3,000sq.ft. and above and is a tiemsaver, time=money.

Once again, the trradeoff is FLOW rate, you will have to determine what is right for your budget, use and setup.

PVC holds up fairly well alone with SH when adding TSP is less forgiving over time degrades but with the Kuri Tec, as in the type in the link I have given, this hose has an INNER and OUTER Jacket plus a middle core (Like a sandwich) which makes it more burst and failure resistant .

It has been discussed here and on other boards about diameter and flow rates and their is no question that 5/8" i.d. is better than 1/2"  but Kuriyama (the mfr.) does not make this type in the desirable 5/8" diameter.

The trade off for 5/8" flow is that this hose 1/2" Kuri0Tec, is more cut and scuff resistant as it is Agricultrural hose instead of food and beverage type.

Air hose, works well also, and comes in 5/8"

But just as NO roof cleaning chemical delivery pump is FOREVER, you will have to INVEST in a new or rebuilt pump or KIT for pump(s) eventually, so it is with HOSE for chemical delivery, AS WELL.

Hoses and fittings and pumps and chemical are your Replacables (Consumables) along with gas and maintenence on your pumps, Gas motors and vehicles.

Just a cost of doing business.


Goodyear Pliovic is also good-

Here is a terrific resource to LEARN ALL about hoses for SPRAY applications
a link to a USEFUL chemical resistance chart for spray hose. Great Info!

Chris likes his 5/8" Kuritec hose.  Yes, a 600psi 1/2" hose will last longer.  I can see it being desirable for gas powered air pumps.  250psi 5/8" hose is pretty good for a small electric pump rig.  The flow loss is considerably more significant using electric pumps going from 5/8" to 1/2".

With a 5gpm electric pump 5/8" hose will give you 3gpm at the nozzle,

1/2" hose will only give you around 2gpm.


How about this one?

Actually, It's funny you mentioned that Mike. Chris does like the current hose he is using, he was using another type, I think it was the Goodyear Pliovic and he had a bad experience where the hose BURST and at a very awkward moment and it was actually me that turned him onto the hose he is now using. I BS you not.

Ask him.

It is a reinforced Air Water handling hose with great Chemical resistancy to SH.

Yes, YOU ARE Entirely Correct Mike.

Kuri Tec does make 5/8" but it is for Air -Water and is NOT made the same as the 1/2" Kuri Tec AG hose that I am found of.

They do make it in 3/4" AG and the stuff is TOUGH.

There is no doubt, 5/8" I. D. flows signifigantly better than 1/2" I.D.
But because Kuriyama doesn't feel they should offer AG hose in 5/8" it is a trade off as air water hose does not have the side wall strength and therefore kinks easier while on the roof and is more frustrating to use at times and is definetely NOT as tough. (Can Ya'll say Hose Mender?)

It's ALL ABOUT FRICTION LOSS and length of hose run.

That will be the main determining factor as to flow at the hoses usuable end, as you know

Is there a reason that you guys are not using 5/8 braided poly line?

If you mean Kuri Tec Clear Poly Braided as in the Food & Beverage type, I use it on one of my rigs now and would use it on all except I got a really good buy on the Kuri Tec orange AG hose last year, also, I use multiple 1/2" hose on MULTIPLE SS and aluminum reels because it is more abrasive resistant and bottom line LASTS LONGER and also so I can have more than one person applying chemical when I need to or, on occasion rinsing where/if appropriate.

Also, as stated in other threads, Braided F&B Braided Poly is more susceptible to blowouts, bubbling, both at the the fittings and connections over time, from chemical deterioration from the SH and TSP depending on the roof mix and also from UV as it is really not made to be out in direct sunlight, day in and day out.

The BOTTOM LINE, from my expreience, is that, Distributing the LOVE shortens the life of most materials other than Kynar.

Ok, I'm getting confused.  I'll have to ask him again, but I thought he said his Kuri-tec hose busted and was thinking of going with the Goodyear Pliovic because it's stiffer, heavier and tougher.

I think he wrote that he's still using the Kuritec hose because he likes it's lightweight and flexibility, and had to cut it down from 300 feet to 225 feet because it busted.

Yes, I remember on PWI you told him about Kuritec, the link you posted I saved on my favorites list, thanks for that.

Anyway, he's working with more pressure than an electric pump.  Electric pumps won't wear out the lighter flexible kuri-tec hose as fast as the gas air pumps, wouldn't you agree?

 

The RED Kurritech hose snagged on some metal flashing and CUT itself.
It was the Pliovic that bubbled and burst!
The remaining 225 feet of the Red Kurritec is still working everyday, after a year.
I LIKE that Hose, flexible, cheap, lightweight, and strong enough.
Yes, AG Hose is tougher, but for ease of use, I like the red Kurritech.
That Dave for finding it !!!

Tropo, I use two tanks, depending on what i have booked for each week. I have a 35 gallon tank that is sufficient for one roof. I also have a 100 gallon tank that works for about 3-4 roofs, depending on size. When that 100 gal is full, the Ford starts to moan a little bit.

I paid $503.00 for my 150 Gl. tank whith aluminum straps ( I had the gaskets replaced) because they were not compatible with SHC. and they will probably leak soon.
is this a fair price?

OUCH, that is a LOT of money to pay for such a small tank IME.
Shop around, you can do a LOT better, at least here in Florida

 

Tropo..What part Of Long Isalnd are you working from? I am out Of Coram.
