Swimming Pool Balance Tank Cleaning Engineers

Along with filtration and chemical dosing, balance tank cleaning is key to keeping the pool water well balanced and safe. Bathers bring substances into pools, which adhere to the water particles causing bio-films to form on the water’s surface. Bacteria can become a problem in such circumstances.

Our Services

We install and maintain the water treatment systems for both private and public swimming pools. We deal with bio film hazards including Legionnaires, Pseudomonas and E-Coli.


All our engineers are fully qualified for working in confined spaces such as filter vessels and balance tanks. We find that maintenance contracts are very popular with our client base.


Water filtration systems, in common with all engineering equipment, deteriorate with age. Our role is to maintain al filtration system so that they function to their full potential.

Bacteria, Legionnaires, Pseudomonas & E-Coli Prevention

Bacteria, Legionnaires, Pseudomonas and E-Coli can grow quickly in pool balance tanks and filters. The PWTAG advise balance tanks should be cleaned and inspected every 12 months.

Prevent Bio-Film Causing Corrosion

Bio-films can lead to a scale build-up on heat exchangers; this prevents efficient heating of the pool water. Bio-Films also cause corrosion of metal surfaces within the pool circulating system, as some Bio-films have a pH of about 1.0 which is very acidic.
