Highly recommend this company, they just custom made/fitted some quality complex underbody water/waste tanks for my motorhome and plumbed it all up. Steve looked after my build, highly professional and extremely knowledgeable.

Steve made and fitted a new water tank for my Kia horizon. Excellent job, very quick professional service. And a very good price. Increasing water capacity from 82 litres to 210 litres

Steve is so knowledgeable and helpful, couldn’t fault the installation of grey water tanks and fresh water tanks. He also did our self containment inspection for the new regulations. Nothing we asked for was a problem as far as what we need for the installation. Great job.

These guys are top notch at plumbing, and water storage solutions for carvanners/motorhomers. Steve at Hercules remedied a few nagging problems with our pre-installed fresh and grey-water tanks, and was more than helpfull in follow up phone discussions. I can't recommend highly enough...they are the experts at this sort of stuff, and well worth going out of your way to get a top job done... Cheers. Tony.

Steve made and fitted two custom tanks in my van conversion. He did a superb job! I could not have asked for better service or a better engineer. Worth twice what they charged me. I cannot recommend them highly enough. Thank you.
