You do need to locate the source of this smell which is almost certainly hydrogen sulphide gas that can be identified in relatively low concentrations, by a characteristic "rotten-egg" odour.
It's usually produced in un-aerated sewage/holding/storage systems.
Although its unlikely the concentration you are dealing with are very high (because you can smell it), it is a very dangerous gas and is not easily neutralised (VicS may know better!).
I would strip down and thoroughly clean/flush all parts of your system, make sure you well ventilate the area before and whilst doing so, and if possible have someone else around when you do.
HS is heavier than air, with a specific gravity of 1.19 and in high concentrations, the ability to smell the gas is lost, the disappearance of the odour could mean that the gas concentrations have actually increased!
There could be something decomposing/trapped in your system that needs to be found and cleared! /forums/images/graemlins/frown.gif

If you can smell H2S (hydrogen sulphide) you are actually over the rec'd Threshold Limit of exposure.
H2S has the horrible habit of deadeing the sense of smell - so you think it's gone but in fact it has not.
It can be due to various factors including grey-water / black-water contamination of systems as well as the naturally occurring biological processes in the fresh water.
A good site that has excellent information about various contaminants in water :

ok - it's USA and aimed at well-water users such as I have at my home ... but looking at pages gives you valuable data about filter types, beasties in water etc. - and it has entire section on H2S ...
