Water tank installation services

At No1PHD, we combine the best materials with our plumbing expertise to ensure that the water tanks we install are durable and fit to your standards. We can work across a variety of tank volumes ranging from the very small all the way up to 60,000 litres.

Every water tank we install is made in the UK and they are designed and constructed to the highest standards, and they are both available in standard sizes and as custom designs for unique situations. Our cold-water storage tanks can be found in small residences, commercial properties and even industrial complexes.

The tanks

Every cold-water tank we supply is either made from WRAS approved plastic or GRP as required by law. Our tanks can be:

  • Sectional
  • One-piece
  • Internally flanged
  • Hot press sectional

A main precaution aim is in fighting against the risks of Legionella growth within your water supply. Legionella is incredibly dangerous and can even be fatal. That is why it is important that you allow a professional plumbing company such as No1PHD to do everything possible to prevent its growth within your home with our expert team installations.

Legionella in cold-water storage tanks

Legionella is a form of bacteria that grows and then multiplies in temperatures ranging from 20 to 45°C which is why when we install our tanks it is our aim to control the temperature and inhibit the bacteria’s access to nutrients. One of the reasons that Legionella is so dangerous is that it can be contracted by inhaling water droplets from the air, causing the patient to develop pneumonia. Normally, a gravity-fed system involves water entering your house through a rising main and then entering a cold-water storage tank before the water is circulated to all the required outlets.

The problem is that stored water carries a risk of Legionella growing if the tank is not correctly maintained. Therefore, it is always best to work with professional plumbers and drainage specialists instead of going the DIY route.

We avoid installing metal tanks due to their susceptibility to rust and corrosion, and instead we rely on water storage tanks built from plastic or GRP so that they last longer and resist Legionella growth. Once a cold-water tank has been installed, we recommend that it is serviced regularly to ensure that it is functionally optimally and that there are no chances for bacterial growth.


Water tank maintenance

Maintaining your water tank is about more than inhibiting bacterial growth. Even water tanks made from the best materials require regular maintenance to ensure that everything is working correctly and to prevent major issues from occurring.

If you ever notice a drop in your home’s water pressure and there is no obvious cause, it could be related to your cold-water tank. The best thing you can do is shut off the water at the mains valve and give us a call so that we can send one of our team to get to the bottom of the problem. Even if you are unsure that there is a problem, it is always best to be safe and give us a call because even small problems can turn into catastrophes if left unchecked. Keep on top of your water tank’s maintenance and you will end up saving a great of money and stress in the long run.

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.
