Commercial Plumbing, Heating and Drainage

A blocked drain or faulty heating in the home can be inconvenient but hardly a calamity. In business, however, simple problems like these can result in hours or even days of lost business and profit. No matter which business sector you operate in, it is vitally important that the correct plumbing, heating and drainage systems are in place and functioning correctly. This is why you should only trust an established firm with a proven track record for any installation, maintenance or repairs of equipment, fittings and fixtures on your premises. It is even better if you can entrust the smooth operation of all your service needs to a single company as any necessary changes or upgrades to existing plumbing, heating and drainage networks can be coordinated and streamlined. This will save confusion, time, money and worry and ensure these three core systems are compatible and deliver optimum performance. No 1 PHD is an established company that covers the Southampton area with a wealth of experience in supplying, fitting, maintaining and repairing plumbing, heating and drainage systems to a wide and varied range of businesses.

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.
