Not everyone has the funds to go out and spend  £100 on a controller if I had the spare cash I would. I have had to splash out thousands this year and big lump of it on a new roof so I'm not being tight with money just can't afford it at moment so need something cheap to get by till next your

These work perfectly - I used them for years and never had an issue: http://www.ebay.ie/itm/2000W-40A-12V-DC-Motor-Speed-Control-PWM-HHO-RC-Controlador-MAX-10-50V-12khz-/322289037255?hash=item4b09ec6fc7:g:CJ0AAOSwOyJX-2kO

Just pop it in a waterproof box (Less than £5 off ebay) and add a fuse - simples.

Very helpful post Nat...Nice one

I don't know how long my two have been going now, but it must be over two-or-three years.

Work every time; no fannying about re-calibrating them when the temp changes; just simply controls the water with no hassels at all.

What pump do you use tosh

[sunshine windows]

I've had the same varistream analogue controllers in my van for nearly 10 years. Can't argue with that for value for money.

What pump do you use tosh

Shurflo 100 psi.

Ok I went to that window cleaning place in Leeds yesterday and the guy actually said that the switch I'm using is not powerful enough to run pump .that the pump keeps burning it out

[dazmond]

if you cant afford a decent pump controller what are you going to do if we end up with 3 weeks of ice and snow?

[jk999]

I can afford it but at mo I have more important things to pay out for like I've had to put a new roof on my house I've had a lot off repair s on my van .had to buy a lot of equipment Latley so I'm penny pinching at mo

[mufcglen]

if your skint and penny pinching pal just get one of the cheap chinese controllers me and someone else posted further up and back it in an electric box,costs less than a tenner,job done

[jk999]

Ok cheers 

[mufcglen]

Honestly for the price of a homemade one pal they're miles better and it is luck of the draw if they go wrong like anything electrical but I used to make and sell loads and maybe had a handful back and I'm certain they was more due to people miswiring them the wrong way round😂
I've had my current one in over a year now going strong still and I keep a spare in the van in case it ever went tits up while out working, its a 2 minute swap and back at it again😎
When I had a spring controller I had to come home start checking connections after I couldn't do a quick fix at the side of the rd and I found I was constantly recalibrating them too, these basic things use the pumps pressure switch to shut themselves off and you can adjust the pressure switch on most pumps anyway, I use mine with a shurflo pump.

That's one off the reasons I didn't like the dear ones because of the calibration all time and they always stopped pumps working on last couple of windows

Some interesting controllers on this thread.
