    I believe only some of the noise can be attributed to case panel reverberation, which is why I think it may be worth putting in some sound absorbing foam sheet, essentially encasing the whole pump area, from the tank shroud back. If I can leave enough clearance for airflow, don't block too many vents, and insulate the boiler, I hope I can avoid overheating the pump (which is apparently a concerb when sound deadening panels etc.).

    On a semi related note, does anyone know a good (cheap) source for:
    - silicone foam insulation
    - small brass valves (1/4" to suit boiler piping)
    - brass fittings to suit the above.

    I've used dynamat before in cars. I presume once the boiler is insulated, heat retention in the insulated case is less of a problem for the pump (I have seen concerns about this on other machines)

    Look into Dynamat for this, there's some other threads about talking about it.

    Hi Mr Jack,
    You are making real progress there...

    I have used a product called "Roadkill" (bought from Autobarn) for acoustic insulation. It works well.

    I agree with Mal...it's A-L-I-V-E!!

    Cheers,
    Paolo

    It's the only bit not spotless! Looks interesting with the camera flash.

    Hopefully not!

    The pump noise is now much better - last night I wedged some sponge between the pump and the rear part of the frame (seems odd the pump is so close), and also between the pump recycle loop and the tank shroud. You can talk over the pump now!

    I also have put a short piece of tube on the waste outlet, as I was getting some leakage into the machine. Hopefully there is no other leaks.

    Thinking of insulating the boiler and then encasing the rear of the machine (behing the tank shroud) in some kind of sound insulation.

    Also need to replace the boiler head gasket, as there appears to be a small leak at the bottom that has led to a buildup of salts/corrosion byproducts along the gasket.

    Doesn't sound like it...

    Cheers.

    I seated the pump properly and its much quieter now. Still some work to do though.
    The 90deg tee was rubbing on the bolt which holds the foot. Still some potential to rub, so will shorten the bolt.

    Way to go "MrJack"...

    These little beauties can produce wonderful quality shots. You're in for a very enjoyable journey...

    The discolouration on the Gicar is probably from the boiler heat. There should be a little heat shield between the boiler and it, but it's only squeezed in there so may have been replaced too low.

    Vibration pumps will make anything rattle that's not tight.
