You get what you pay for... Needs a bit of work to get opperational.
on 30 December 2014
I had a good look at the reviews before I bought this so I should have been prepared for this rather than hoping "it might not happen with mine" but it seems like this suffers from a design fault. As with many other reviewers I experienced air leaking. This means it can't hold any pressure and very quickly goes from a nice spray to a limp dribble.
The leak was fairly easy to locate, it's the pressure release valve. It's easy to take apart (remove the white clip below the spring, slide the spring off the pull the red bung out) and inspecting it all the components were in good order so I think it's in design rather that I received a fault unit. When it does have any pressure the slightest brush against the valve and you hear a rush of air coming out, it just seems to create a very tenuous seal at best.
As I say it seems a design flaw, the o-ring is fairly small and there seems a lot of wiggle in the stopper. Slathering it in Vaseline did help but not entirely. It allowed me to get the job I needed done out the way at least. I'll not need to use it again for a while but the next potential culprit I'll try tackling to improve the seal is to put a washer or two at the end of the spring to increase the tension - that should hopefully help counter the higher pressure and allow a bit more to build before a leak - or dig around my odds and ends to see if I have a beefier o-ring (not spares in mine as another review commented) but it's workable with the vaseline.
Now I bought this having read numerous reviews of pressue leaks/quick pressure loss so I half expected I'd experience the same. If I didn't though, I'd have given it 1 star. Still, you should expect something you buy to work, right? Yes and yes it does work, just poorly. For context though Argos's cheapy own brand is over double what I paid for this, B&Q's cheapest equivalent approaching triple of what I paid and I suspect with a bit more work on the valve it'll operate absolutely fine and still at a much cheaper cost than the alternatives so 3 stars. I got what I paid for.
Having gone back to it and reapplied Petroleum Jelly to the pressure release valve with a bit more care (rather than in frustration while trying to use it) and it now works 100% as advertised. Hold pressure well, builds up as far as it said it should and can go for ages without having to stop and pump the pressure back up. Brilliant!
