Commercial descaling and fat removal

For Southampton businesses dealing with food preparation, blocked sinks are almost inevitable. No matter how careful we are, fat still builds up until the problem must be dealt with. Between the little pieces of food that escape from plates and the little bits that come from the dishwasher, a fat buildup is all but unavoidable.

At No1PHD our Expert Drainage Technicians have all of the equipment and experience necessary to deal with blockages caused by fat buildups. We utilise high-pressure water jets combined with a variety of specialised nozzles depending on the precise nature and location of the issue.

We seek to clear all debris by unblocking drains in Southampton fast with or professional methods by drainage experts you can trust.

Grease Traps

For businesses in the Southampton area interested in preventing these fat-based blockages from occurring, we offer grease trap installation services. These catch fat, grease and most solids before they enter your waste-water system where they cause blockages. Once installed, it is vital that you have your grease trap emptied and serviced regularly to make sure that business can always continue as normal.

If you are unsure about whether or not you should install a grease trap or what kind you need, then give our Southampton office a call. We have fat, oil and grease management specialists on hand who will be happy to assist you in figuring out what your requirements are. Our team can advise you on the appropriate type of trap that best suits your requirements and create a system for regular maintenance so that the traps always function.


Fatbergs are the nightmare scenario for businesses and even residential properties. Despite the knowledge and warnings designed to prevent them, they continue to build up until drains are blocked. Too many people simply pour oil, grease and fat down the sink until fatbergs form and a blockage ensues. In businesses like restaurants and commercial kitchens, fatbergs go from being an inconvenience to a major problem that causes serious disruptions to service and even has negative consequences for health and hygiene.

No1PHD is a registered waste handler equipped with everything required to handle even the biggest, most stubborn fatbergs. We use our advanced jetting equipment to dislodge the fatbergs and cut them down to a size that allows the chunks to be easily removed.

Once we have removed the fatbergs from your drains and waste-water systems, we transport the chunks to registered waste disposal sites so that it can be disposed of in the proper way. We will fill out all of the required legal documentation on your behalf so that you can continue to focus on your business without worrying about meeting your environmental management obligations.

Couldn’t have asked for a faster resolution to our drainage conundrum. Nothing was too much for these guys who were brilliant throughout.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
