What is included
Water tank cleaning and disinfection for villas, apartment buildings and commercial sites, with every tank drained, scrubbed, disinfected and photographed. Stored water sits in Abu Dhabi heat for most of the year, and sediment, biofilm and algae build up in tanks that are rarely opened. Our own team drains, cleans and disinfects the tank, flushes the lines and checks the lid, vents and float valve. What your building or the authority asks for in records or certificates is checked at the site visit.
- Inlet isolated and the old valve, arm and float removed
- New valve matched to the inlet size and the supply pressure
- Shut off level set a clear distance below the overflow pipe
- Tank filled and the valve watched through a full open and close
How we carry out water tank float valve replacement
The inlet is isolated and the water level lowered below the valve. The old valve is unscrewed from the tank wall with its backnut, and the opening is cleaned of scale so the new washer seats flat. A replacement of the same inlet size, suited to the supply pressure, is fitted with the float arm set so the water stops a clear distance below the overflow. The supply is opened, the tank is left to fill, and the technician watches the valve close fully and reopen when water is drawn off.
Float valves fail slowly. Limescale from hard desalinated water builds on the seat until the valve weeps and the overflow runs all day, or the float takes on water, sinks and never shuts. The opposite fault is a valve jammed closed by grit, noticed only when the taps run dry. Because the tank is open for the work, hands and tools are kept clean, and a disinfection is advised if anyone has had to enter. The site visit checks the isolation valve, the overflow route and the inlet size.
How it works
The same method on every job, so the result does not depend on who is on shift.
- Survey and diagnosis. A technician inspects the system or surface, takes readings and photographs, and explains what was found in plain language.
- Written quotation. You receive a written quotation against a defined scope before any work starts. Anything outside that scope is quoted separately.
- Protected, supervised work. The work area is protected and isolated, and the job is carried out by our own technicians under a named supervisor.
- Testing. Every job ends with a measured test suited to the discipline, so the result is a reading and a photograph and not an opinion.
- Report and warranty. The completed report reaches you within the hour. Any failed point is put right free of charge within 48 hours.

Water Tank Float Valve Replacement in Al Mushrif: what we plan for
Al Mushrif is a long established villa district in the centre of Abu Dhabi island, between Airport Road and Al Khaleej Al Arabi Street. Most homes are standalone family villas on their own plots, in areas such as Al Qubaisat and along Al Saada Street, with compounds including Mushrif Gardens, Palm Oasis Villas and Al Yasat Compound. Umm Al Emarat Park and Mushrif Mall sit within the district.
Mature trees and large gardens give Mushrif more shade than most of the island, but they also bring leaf litter, pollen and birds. Irrigation keeps garden walls damp at the base, and dust from open plots and building work settles on terraces and in AC filters. A typical Mushrif villa has ducted and split AC units installed at different times, along with water tanks and pumps. We map the equipment first, clean ducts and coils, and check tanks for the sediment hard water leaves behind.
Standalone villas are reached directly, with the owner or house manager present for the first visit. Compounds such as Al Yasat and Palm Oasis have gate security, so the resident registers the crew in advance. Approvals for exterior work are identified at the site visit and we prepare the paperwork.

Questions about water tank float valve replacement in Al Mushrif
What does water tank float valve replacement include?
A float valve that sticks either floods the roof through the overflow or leaves the tank empty. We replace the valve, arm and float, set the water level and test it over a full fill. The work includes inlet isolated and the old valve, arm and float removed; new valve matched to the inlet size and the supply pressure; shut off level set a clear distance below the overflow pipe.
Does the tank have to be drained to change the float valve?
Not fully. The level only needs to drop below the valve, which sits near the top, so most of the stored water stays. If the tank is due a clean anyway, doing both in one shut down saves a second interruption.
My overflow pipe drips all the time. Is that the float valve?
Almost always. A constant drip or trickle from the overflow means the valve is not closing at the set level, because of scale on the seat, a worn washer or a float that has filled with water. We confirm it by lifting the arm by hand.
How much does water tank float valve replacement cost in Al Mushrif?
We do not publish prices, because no two jobs are the same. The main factors: size and type of the system or surface; present condition and ease of access. Book a site visit: a supervisor from The MELLS looks at the work and you receive a written quotation with a defined scope before anything begins.
Who provides water tank float valve replacement in Al Mushrif?

How long does water tank float valve replacement take?
Typically 2 to 4 hours for most villa tanks, and up to a full day for large building tanks. The time for your property is confirmed with the quotation.
How long will our water be off?
For most villas the supply is off for a few hours while the tank is drained, cleaned, disinfected and refilled. Buildings are planned with management so residents have notice, and twin tanks are cleaned one at a time where possible.
Is the water safe to use straight after disinfection?
The tank is rinsed and the outlets are flushed until the chlorine reading returns to a normal range before we hand back. You may notice a faint chlorine smell for a short time.
Will we receive a certificate?
Every job ends with a written report and photographs taken before and after. Where a laboratory test certificate is needed, a sample is sent to a laboratory and the result is passed to you.
How do your crews get access to Al Mushrif?
Standalone villas are reached directly, with the owner or house manager present for the first visit. Compounds such as Al Yasat and Palm Oasis have gate security, so the resident registers the crew in advance. Approvals for exterior work are identified at the site visit and we prepare the paperwork.
Do you work with house managers and household staff?
Yes. The supervisor agrees the plan with the house manager, works zone by zone and walks each area with them before the crew moves on.
How do I choose a company for water tank float valve replacement in Al Mushrif?
Ask four things: who employs the people who will come, whether the scope is written down before work starts, how the result is checked, and what happens if something is missed. The MELLS uses its own staff, quotes in writing after a site visit, checks every job (a measured test for every job, with photographs before and after) and puts right any failed check free of charge within 48 hours.
