Pool pump rooms and equipment upgrades

Replacing and simplifying pool equipment

Many villa and hotel pools suffer from ageing pumps, leaking filters or tangled pipework added over time. When equipment fails or confuses staff, we remove redundant lines and rebuild the circulation into a clear, workable layout.

When we upgrade a pump room, we can keep your sand filter and refill it with PebblePure glass filter media. It is used in place of sand when the grade, quantity and layers are matched to the filter. Filtration removes suspended debris. The pool still needs disinfection and water balancing. Results depend on the filter, flow rate, installation and maintenance.

• Replacing worn filters and converting old media systems to sand filters
• Installing quiet variable-speed pumps, salt chlorinators and UV sterilisers
• Stripping out broken air blowers, disused spa loops and redundant valves or inlets
• Rebuilding automatic water top-up lines and replacing seized shut-off valves
• Fitting acoustic panels, anti-vibration mats and variable-speed pumps to cut noise near bedrooms and terraces

Flood protection and underground pump rooms

Underground pump pits in Phuket often flood during monsoon rain, ruining motors and electrical boards. We rebuild flooded pump rooms and protect vulnerable underground plant before water rises.

Never enter a flooded pump room while the power is on. We decide which measures suit each site after an inspection, and all electrical work — including isolation, earthing, earth-leakage protection, switchboards, level switches and pump supplies — is carried out by a licensed electrician and agreed with the owner. Where moving or rebuilding a plant room involves structural work, we plan it with you and your engineer — or, if you don't have one, with our partner engineer.

• Moving the entire pump room out of an underground pit to ground level or an upper floor, with the hydraulics designed for the height above water level
• Raising pumps onto plinths above floor level inside existing plant rooms
• Moving electrical switchboards out of damp pits into weatherproof outdoor boxes
• Waterproofing pump room walls and floors from the inside where groundwater seeps in
• Two or three back-up drainage pumps set at different levels and on separate power supplies, with level switches that cut power to the pool equipment if water rises
• Low-voltage battery pumps as a last line of defence, not main drainage, if the 220 V supply fails
• Emergency drain pumps for overflow tanks that were built without an emergency overflow
• Air conditioning and ventilation to control humidity

Draining, pool use and site organisation

How we stage the work depends on your valve layout and where the pump room sits relative to water level. An on-site inspection decides whether the pool stays filled or must be drained; wet-season or high-groundwater conditions need assessment. Hidden problems in buried pipes or structures may only appear once work starts, so work can go in stages. The programme is agreed for the individual project.

• Pool stays in use or water is lowered: replacing pumps, filters, chlorinators, switchboards and acoustic lining when valves isolate the lines, or building a relocated pump room before final pipe switchover
• Pool must be drained: rebuilding main floor drains, altering buried shell pipes, waterproofing inside the pool or balance tank, or raising a flooded pool edge
• Who decides what: we inspect the plant, explain what can stay and agree the setup with the owner, villa manager or hotel engineer

What to send for a first discussion

Send us these details so we can review your setup before visiting the site.

• Photos or a short video of the pump room, switchboard, pipes and pool
• The property location and approximate pool size
• What you want changed, such as flood protection, quieter running or simpler maintenance
