    so ran a wee test this week

    we use shurflo pumps from 8 odd till 5 or 6 in evening they run all day wen pull the valve the water stops and they stop sweet

    so we changed a pump out to these cheaper ones

    bascially they work

    but wont go like the shurflow

    after around 6 hours they overheat and thats a wrap lol
    think these be ok for the odd job here and there as the flow is good Aand so is pressure

    pete ive used these since i started, (never had a shurflo) ive gone through 4 in about 18 months, this is combined on the van mount and on the trolley, for 11 quid each i dont think thats bad. 2 of them still work but have lost a bit of power, they are fine for the trolley though.

    Only thing i found is theres not quite enough flow rate for 100m microbore, i have been using about 70m on the reel and found the flow on full about perfect.

    However ive just bough a new reel with 100m microbore so i bought one of these...

    DC 12V 130Psi High Pressure Diaphragm Self-Priming Water Pump 5.5Lpm 80W

    130psi @ 5.5Lpm, dont know how long it will last but the pressure is better than the 4lpm one was through 70m hose.

    Really don't get the logic here. Keep buying cheap ones that keep needing to be replaced, or pay up and get a 100 psi shurflo that are built like tanks and will gush through 100 metres of microbore with ease plus last for ages if looked after properly. Mines coming up to 9 years old and still pumps like Ryan giggs :thumbsup:

    Agree with peter rogers and steve garwood
    Once you do buy a shurflo pump, you will not want to use anything else. I have found the cheap pumps will last around a year on DIY Trolleys, and it was that reason that I made the Heavy duty Trolley. As well as the reassurance that the pump will not break down, it is also very quiet and can hardly be heard when working.
    I still use a Trolley with a cheap pump sporadically, for gutter cleaning or conservatory roofs. I pump cleaning agents through it, then flush it with Tap water when finished. Sounds like a pneumatic drill compared to the shurflo but serves a purpose.
    My advice for what it's worth is to get a Shuflo pump. They are more expensive but not in the long run, and much better to use.
