For more challenging work we use our ‘City Flex’ Tanker for commercial customers. Designed to clear larger diameter pipes (up to 450mm dia) it packs the same drain cleaning punch as a standard jet vac tanker.
For city and urban sites this is the best kit for the job.
We can get to building and industrial sites, along access roads, around commercial sites, as well as height-restricted sites.
We offer a local tankering service, fully equipped to deal with all eventualities.

Unblock Drain
"Communication was before & after the work. Wayne was very friendly & did an excellent job."
Unblocking drain
"Having used Happy Drains previously, I contacted them about a blocked drain on my property. They responded immediately, sent engineers who were prompt, professional and friendly and had the job done in 25 minutes. Just to top it off, the price was the same as my last call-out with them two years ago. Excellent service all round."

Severe drain blockage cleared fast
"We used the Basingstoke branch, and I couldn't be happier. We had a severe blockage in our main waste pipe due to previous owners dumping grease for years. I called in the morning, they came just after lunch. The engineer was friendly and knowledgeable and explained every step thoroughly, cheerfully answering my questions (I'm curious about everything) and did the job quickly and with a great sense of humour, letting me fill the fatburgs that flowed out. Price was brilliant too. Couldn't recommend enough. "
