I cant comment on flannigans although its clear to see its failed where its most important..

With riches (sonic boom)i can say that the welds are shit and its a very poorly made bit of kit as i did see this first hand..

There is no need to re invent the wheel when it comes to these gated baffles as like iv said before the ones iv used for many years are fine and never seen or heard of any trouble..

They are also not dear to buy.. also to flannigan..id say theres nothing wrong with your actual sump mate just been very unlucky with the gates on the baffle..



cheers danny
