Southampton Bathroom & Plumbing Installations

Proper working plumbing systems are vital for the day-to-day running of any office or home comfort. They ensure proper water supply, wastewater management, heating and other essential systems are running right. However, they need to have been installed right for them to run effectively. At No1PHD, we offer a wide range of plumbing installations, depending on the use and individual needs. If required our emergency plumber Southampton services are available 24/7. We can advise on equipment selection and house design to ensure optimal use of materials and efficiency.

Our Plumbing Installation Services

Here is a selection of some of our plumbing installation services we offer our commercial and residential clients.

Toilet Installation

If you are building a new apartment or updating your bathroom fixtures, we offer a full toilet installation that includes water closets, faucets and sinks. In addition, we install bathtubs and overhead showers for your bathroom. If your toilet is not water-efficient, we can install new water-efficient ones to help lower your water bills.


Water Heater Installations

If you would like to have a hot water system for your showers, laundry, or dishwashing, we can install electric, gas, or solar water heating system. If your water heater has been around for nearly a decade, it may be time you thought of updating it to a new efficient one that comes with minimal costs.

In addition, we connect your hot water systems to dishwasher showers and any other appliance that may require hot water. We can also connect such appliances to the regular water supply system and drainage for appliances as dishwashers and washers.

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

Boiler Installations

We design and install full home heating systems that includes boilers. Our boiler experts also replace inefficient or malfunctioning boilers. We can also replace parts such as the boiler tank airlock and diaphragms for the existing boiler. Besides, if you would like to switch to a gas boiler or an electric one or vice versa, we can do the replacement for you.


Installation of a Venting System

If you have combustion appliances at home, proper venting is vital for good air quality and the safety of the occupants. Our Southampton venting technicians can install direct venting to the outside for appliances as exhaust fans, stoves and heating units around the house.


Backflow Prevention

Backflow is a sudden change in pressure where contaminated water from the municipal or sewer line gets back into the house or office premises. A backflow prevention system is installed in areas where there is a likelihood of such a phenomenon. If you have experienced a backflow or are susceptible to one (such as the cases where you live below the municipal line), we can install a backflow system that complies with the local authority building codes.


Kitchen Faucets Installation

We replace leaking kitchen faucets along with sinks and drainage systems. If you are experiencing water leaks, a replacement of the piping may help prevent water loss and resulting in lower water bills. On the other hand, the installation of a drainage system, including the piping and gullies, prevents flooding and contamination of your home by dirt water.

Installation of New Sewer Pipes and Manhole Systems

If you have already built a new structure, you will need to connect the plumbing system with the new sewer line and drainage. We can excavate, lay pipes and ensure that the ensure drainage system of the new building is connected to the sewer system.

In the same breath, we can replace any plumbing and sewer pipes that are damaged beyond repair. Besides, our Southampton plumbing teams can also replace the old lead pipes that may now be too small for your wastewater management needs or those that might have been corroded, causing repeated blockages.

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.
