Portsmouth Toilet Cistern Replacement Services

The cistern is the core of the toilet flush system. The entire water storage and flushing mechanism are hidden inside the cistern with just a knob on the outside for flushing purposes. Our No1PHD toilet installation experts for Portsmouth residents can replace your cistern if it has issues that cannot be repaired effectively. We believe that quality cisterns are not only efficient but should also look good and enable flushing with ease.

Common Reasons Why You Should Replace Your Cistern

  • Cracks and Leaks from the Cistern

Most toilet cisterns are made of plastic, marble and clay, all of which can break when too much force is applied on the cistern. When the reservoir cracks, small amounts of water can keep dripping onto the floor or the subfloor and may eventually damage the floor. Besides, leaks may drive your water bills up within a short time. Therefore, it is vital that you hire our plumbing technicians for cistern replacement as soon as you notice any leaks from the cistern.

Poor Water Efficiency

If you still have an old toilet that was manufactured up to the late 1990s, there is a high chance that it is flushing lots of water down the drain. Fortunately, No1PHD cistern installers can replace your entire toilet with the new, water-efficient models. These new models use less than two gallons of water per flush as compared to four gallons in the old toilets. They also have half-flush and full flush features to cut down on water usage. This, in turn, helps conserve water and lowers your utility bills.

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

Over time, hard water may form scum inside your cistern. The dark line is usually an eyesore that does not come off easily, even with regular cleaning. Calcium deposits may also cover the entire flushing system after a long period of use and make it hard to move. If you have used your cistern for a considerable period and you start to find stubborn stains, consider replacing it with a new, easy to clean model. Our plumbers can check your cistern and advise accordingly.

On the other hand, you may hire our Portsmouth toilet experts to replace your cistern if you renovated your washrooms and the toilet does not match your new style. This could be due to the aesthetics or the difference in colour. Fortunately, toilets come in a variety of colours that can match any style or décor.

Broken Components

Some cisterns come with unique flush components that you may not find out are there. Other times, the cost of replacing such units is usually too high and close to buying an entire unit. In such scenarios, our Portsmouth plumbers may recommend buying a new cistern altogether. In fact, with the new unit, you are assured of efficient operation for longer when compared with replacing one or two parts in the flush system.

No1PHD Also Carries Out Entire Toilet Replacement

If you would like to replace the entire toilet and not just the cistern, our Portsmouth cistern installers can also replace the entire toilet for you. This may be important in cases where both the cistern and bowl have been damaged, during a toilet renovation or when you need a more comfortable or water-efficient toilet. We have access to a wide variety of toilet designs with various features from which you can pick a toilet that fits your needs. Besides, we carry out comprehensive plumbing installations and repairs for the entire building; be it a residential property or commercial premises.

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.
