I feel as though this is a rough way to look at the situation but my apologies if there's been a misunderstanding. I don't blame Aquacomputer (the manufacturer) as I didn't buy from them, in fact I haven't gotten a response from them on the matter at all.
I haven't taken the pump out because I want to secure a resolution in the case that it's not a simple case of some debris that needs to be removed. I did say a few times that I can't have my PC offline for multiple weeks. Aquatuning are the crowd I bought it off and they are not answering any of my questions. They haven't even agreed to replace or refund the product if I send it back. They've just told me to send it to them at my own cost, and when asked other questions I was told to send it to Aquacomputer at my own cost instead, again without any agreement to refund.
So lets say I go through the trouble of setting up the workbench, moving my PC, draining my loop, pulling parts out and removing the pump right now. If it does happen to be something that is easily fixed, then fantastic. Lucky me. I put the pump back in and all is well. ...But we don't know that, there is just as much chance it's faulty and needs to be replaced. To me it sounds like electrical noise, but I could be wrong.
If it is faulty as I suspect, I have to stick it back in the system again and refill the loop so I have a running PC until I sort out this stuff with Aquatuning (who are very unresponsive) and then take it out again and send it away once I finally convince them to comply with our consumer laws and cover the return costs. It's just extra work that's unnecessary.
To me the ideal order of doing things is to sort out the return path with Aquatuning first, remove the pump, if it's faulty then return for a refund and buy another pump.
So to summarise, what I want is to have confirmation from the retailer (not the manufacturer) that if the pump is faulty as I suspect, I can send it back to them for a refund, without being penalised with international postage costs.
