    Primaflow cp6. . Not circulating the water so boiler is switching off in a few minutes as temperature gets too hot.

    Plugged in ok. no more than 3 years old.

    Is that something I could take a look at myself, or when theyre gone theyre gone? Power going into it ok.

    How much are they? Is replacing them straightforward, drain system, drop new one in?

    found it online which wasnt easy so Im guessing it was just a cheapo one that the plumber put in at the time, cant get a hold of the guy now. Would cost at least 50e to get a fella to look at it anyway so not much point.

    If I can get a new one for under 100, is it a straight forward lock the valve either side of the pump, drop in the new one and wire it up making sure the water is going the right way?

    can anyone recommend me somewhere that I can pick one up on a saturday around dublin/tallaght?

    If the valves on either side of the pump are the slotted-screw type, it's very likely that one or both will leak after being disturbed. That would mean a drain down and replace with proper wheel-head type valves.

    They are slotted head, thanks for that.

    last one I had must have gone on for better part of 10 years but I guess this one went cos at that price its cheap it looks like.

    Could you recommend a decent one that will last a few years that should be available in a local suppliers? Are all domestic pumps the same size and fittings?

    Check or clearly photograph the label on the pump to get the required head (also take note of the switch setting if its that sort and pumping direction) bring those details into a plumbing shop, like Chadwick's or Heatmerchant's etc. and they will supply you with a suitable one.

    In your case, I would have a plumber do it and ask him to change those valves at the same time.

    For around the €100 mark you should be able to get a DAB, a Loware or a Heat Merchants own brand.(~~€90). The "better" ones like the Grundfos UPS2 or Wilo will probably cost €20 to €50 more depending on where purchased.
