Emmett45 Posted May 23, 2017 Share Posted May 23, 2017 Hi all, I have a fairly old Sound Lab snow machine. It was recently fired up for the first time in a long time and despite it being set to maximum the output wasn't fantastic. Is there something recommended to flush through the machine in order to get rid of the old fluid and any residue? Link to comment Share on other sites More sharing options...
ImagineerTom Posted May 23, 2017 Share Posted May 23, 2017 Take the sock off the front of the machine, inside there will be a little ariation stone/block on the end of a piece of pipe. Take that out (carefully) and clean it thoroughly as they often gunge up. Reassemble. If that doesn't fix the flow then the pump probably needs replacing - snow/bubble liquid is very corrosive and gungy; left alone in a machine for a few months it can destroy seals and fur up metal components inside a pump.

Ynot Posted May 23, 2017 Share Posted May 23, 2017 There was one that sat in unused our stores for quite some time that when it was brought out for a show it failed as the piping had also become very brittle and broke very quickly when a clean was attempted.

Emmett45 Posted May 25, 2017 Author Share Posted May 25, 2017 Hi, The little aeration block is actually missing off of the piping. This, I imagine, does not help matters. Take the sock off the front of the machine, inside there will be a little ariation stone/block on the end of a piece of pipe. Take that out (carefully) and clean it thoroughly as they often gunge up. Reassemble.

ImagineerTom Posted May 25, 2017 Share Posted May 25, 2017 Not the end of the world but not helping either. The block ensures that the fluid spreads evenly around the inside of the sock, without it the fluid will tend to clump at the end of the sock producing less, wetter snow Link to comment Share on other sites More sharing options...
bigclive Posted May 26, 2017 Share Posted May 26, 2017 The snow fluid is not great for the pump in storage. (I wish they'd make these things with peristaltic pumps!) The main pump issues are:- Swollen o-ring in the piston seal which restricts movement.General gunking up of the flow valves.Tendency to block at the right angle on the pump outlet if it's that style of pump. All these require careful disassembly of the pump to check (It has lots of bits and a spring!), but it's probably cheaper time and result wise to just replace the pump.

Emmett45 Posted May 26, 2017 Author Share Posted May 26, 2017 Is there something that would serve as a suitable replacement? Filter from a smoke machine etc?Not the end of the world but not helping either.

alistermorton Posted May 26, 2017 Share Posted May 26, 2017 Would an aquarium air stone work if it could be bodged on? I've not used snow machines so I'm clutching at straws here. Link to comment Share on other sites More sharing options...
ImagineerTom Posted May 26, 2017 Share Posted May 26, 2017 That's exactly what they usually are Link to comment Share on other sites More sharing options...
