Sounds like the pressure setting just needs to be increased  ???

Im gonna put my neck on the line here and say its your battery.
Try giving it a slow charge with a decent 8 amp charger for minimum 12 hours.

Thought it might be the battery too coz  Id heard that varistreams are quite voltage sensitive, so charged it up with a smart charger at 8amp for most of a day until it read 100%.
Just tested it again and it's still 100%.

Ive got quick release leisure terminal clamps on it to ensure a good connection.

Could it be that the feed from the battery to the Varistream is not big enough to draw the amps through?  Its got 1mm 17/18 amps on it now, urm,  I think.

Tomorrow Im getting some more O clips for the pole hose/valve connection, to be sure that's not leaking.
And I'm going to try the water through the pole hose without the gooseneck in case it's pinching the pole hose up at the top.
But before then I need some sleep.  And a good drink.  Thank you

I know you must be getting peed off with it now but im sure you will get to the bottom of the problem.
From what you have described it sounds to me as if theres not enough power in the system to maintain a constant pressure.
That could be due to the varistream setting, bad electrical connection or low battery power.
All cables should be a minimum 10 amp rating.
If water is coming through it cannot be a blockage in the system.
And if it works ok and then gradually gets worse I would think its because of one of the above.
You could try swapping the leisure battery with a good car battery as a temporary measure and see if you notice a difference in performance.

When I closed my eyes last night I could still see a spaghetti of hazard yellow pole hose burned into my retina. :o

Thank you for the reassuring words in your last post...it gave me hope!

This morning I redid the connections from the battery to the Varistream.  (It's 1.5mm multistrand by the way not 1mm as I thought before.) Just trying to eliminate any causes that end. Well, you never know.  Battery still 100%.

We tested it out again as far as the valve - OK
Tested through the valve - OK
Connected the pole hose - Bit tempremental
Hmm has it got a kink in it I wondered.
So tried it through 10m of new pole hose Id got for spare  - Bit tempremantal again.

So it seems to go through 100m of microbore internal diameter 6mm without a hitch and then meets resistance in a few piddly extra metres of brand new pole hose which has outside diameter 8mm / internal 6mm. ???

Managed to get a fairly constant flow by increasing the pressure to E and lowering the flow to 3.  Not a great rinse, but 4 had too much splashback.
At that rate the pump was running very quietly so there might be an advantage in that its unlikely to ever overheat.

Cant test it out properly and actually earn any money because with all this checking/undoing/redoing I have now run out of  O clips.  Not going back to jubilees now!

Tomorrow the new clips should arrive. And should I live that long, I will let you know how it goes.

Thank you.

Just thought of something else, if you use a Gardiners supplied angle adapter that has been drilled for the hose. Check that it's not squashing down when you screw the adapter on. Mine was for two years before I realised - just drill the hole bigger and further away from the threaded bit so that when all screwed tight you can still pull the hose back and forth.

Just been reading through all the posts and no one has mentioned this so I'll just throw it in. Have you checked the female Rectus connector that you plug the pole hose into? I recently had an identical problem to what you're described (worked fine for some houses and then the Varistream started having tantrums) and it turned out that some resin had got into the hose and had jammed up the connector. I couldn't see it until I took the connector out of the hose. Once I cleaned it out (a one minute job with some water) all was well.

Thanks for all the help, gettin' there, we can use the system now albeit on one setting. Will check that tommorow Craig, cheers  ;)

Ha!  Could you tell that the boss wrote that last post?  What's with all the missin'  letters off the end of the verbs? Huh?!
Yes I think you're right, the neck does need drilling out a bit more.  Will get onto that pronto.

Thank you for all your help.  Especially for the optimism that we would eventually solve these problems.
We have now earned 65quid! Woo! 8)

Since the system is working at the moment, it's a case of If it aint broke... But it would be nice to be able to use some of the other settings, but hey ho, it runs.

I have got some more O clips on order.  They definitely make a better seal.

So thanks once again.

Hope you will still be there for our next crisis of confidence!

My Varistream digital is temperature sensitive. I have to increase the cut off pressure when it's near to freezing as the water gets thicker.
So you have checked through everything, and it works OK until it reaches the pole hose, You know it's not blocked as it sometimes works OK.
It all comes back to the varistream settings.
 Varistreams can go wrong, and Williamses won't take any responsibility if you are using microbore hose

100 meters of microbore coiled on a reel offers a hell of a lot of friction, it slows the flow of water as it presses against the sides of the hose, think of the pressure on your side as you go down a helter skelter, you would go a lot faster if it was a straight slide.
Varistreams were never designed for microbore hose, I use it but only have 30 meters on my trolley hose reel. I bet your system would run on a much lower pressure setting if all your hose was pulled out in a straight line.
Maybe your solution is to use 8mm mini bore hose, or have a smaller reel for doing the jobs that arent to far from the van.

Hi Dai,

I think that this is the problem. Hydrophyl also mentioned it earlier. There is no mention of spluttering at the brush head with air being pumped out. As they turn the flow right down to problem goes away. I have had to raise my cut-off pressure on my digital varistream this winter as well.

We have been using Shurflo pumps and Varistreams from Williamson's with minibore hose since the beginning and haven't had the slightest issue with pumps. If the pump stops working the battery is usually the suspect.
