I have been WFP since August with a van mount. It has been a huge success with the customers and my ladders are now (thankfully) a thing of the past.

Before my query here is my set-up so you know the score:

650 ltr
SHURflo 8000-946-138 - 110 amp Leisure
Varistream Digital
11 ltr Resin Cannister
100 mtr mini-bore
23ft Unger Pole

When I bought the system the seller stated he generally used setting 2. Even on first cleans I found this to be adequate but 2 months in had to go up to setting 3 for the same flow.

Now, just after Christmas I have had to go up to setting 4. That means for commercial or really dirty first cleans I am having to go to setting 5 or 6 which I don't want to do as it puts undue pressure on the pump. When the flow drops one of the jets begins to trickle and a shake of the pole would correct it.

As it turns out, and despite the fact that I have had to go to setting 4, the flow is consistant and works well at all levels. But how long till I have to go upto setting 5?  I've heard good and bad things about the Digital Varistream, now my round is accustomed to WFP varying flows aren't as important as it used to be.

Help and advice would be handy, people have given me advice before and I have faith in you again!

Charge your battery.

The numbers don't mean anything.

I recently had the same problem. Battery fine, Varistream fine, but pump had got a bit noisy - I ended up replacing my pump. Its fine again now.

[Dean Taberner]

Its because of the cold,

You will be back to the 2/3 flow rate in the summer.

Thanks everyone.

I have been concerned about the level of power in my battery but as long as the green light doesn't flash I thought it would be okay. I generally work for 2-3 days then carge it over-night.

The most I have charged it for is two days but want to be careful not to burn out the interiors. It is an older type charger that charges at 2 or 2.5 AMPS.

I'll see how things go and the cold weather has crossed my mind. Cheers folks.

Im not saying this'll sort your problem out but if you charge the battery daily it might help.

Cold weather - more resistance in the hose, water is thicker too when cold. I had so much flow in the summer that everything was set as low as i could get it, now i'm on 4.
You'll notice that kinks in the pole hose will remain as a restriction too.

[Oakley Windows]

Yea, saying that things seemed slower today flow-wise, even out of the 200 litre drun into my barrels.

if your pump has a pre filter it may have become slightly blocked , try removing the filter and cleaning it worked for me when i had same problem.

My sensor takes several seconds to realise that the valve is fully open. I was waiting for water at the brush head on every job today.

[WISEOWL]

Looks like it is more common than I thought. 

Incidently the pressure setting is on C and I have changed it up and down more out of curiosity and seen no real difference so have left it at the same pressure setting.

Oh and nearly forgot!

Setting 3 - 850ml per minute
Setting 4 - 1200ml per minute
Setting 5 - 1600ml per minute

Which led me to believe that nothing conspicuously wrong with the set-up.

Hi
I agree. At 4 to 0 degrees water is changing from liquid to ice and so becomes more dense. I also find that my 2 pumps running from a 120amp leisure battery are also struggling as the efficency of the battery deteriorates with the lower temperatures as well.

I'm going to check it at the weekend. Is it the black lid you just unscrew and what am I looking for once I am inside?

Yep, this happened to me, cleaned it and all was well.

could try the following, test to see if its your battery,
use pump off another battery you know thats good
clean out diaphram on pump, just take head off and take everything apart, its really easy and clean, should have a filter, got one off ebay 7 quid, before pump, because any bits that get into diaphram will effect flow.

Yeah!

I can imagine me with 364 bits of metal on the table!

 

[jonisondell]

no dont worry there's not much in there only a few bits of plastic, it all comes apart really easy, ive done it a few times its really simple you cannot go wrong, ive got a parts diagram if you want it shows how it goes together

[WISEOWL]

I should be okay if its just a case of taking it off and putting it back on again.

What does the diaphragm look like? Is it near the top of the pump or with the metal cannister...

[jonisondell]

the diaphram is the plastic bits its what does the pumping, just take head off and take it apart easy peasy
