CLEARMASTERS
Riverside pump servicing
Homes on the Thames, Mole and Ember often depend on pumps. We service them before winter, test pumps, floats and alarms, and respond 24/7 when one fails.
Learn moreHampton Court sits where the River Mole and the Ember join the Thames, with the palace and Bushy Park on one bank and East Molesey and Thames Ditton on the other. Many homes here are right on the water or on low ground behind it, and rely on pumps to get waste to the sewer and keep basements dry.
Our work here is mostly riverside: servicing pumps, clearing and surveying drains under period homes, and pumping out flood water when river levels are high. Pubs, cafés and restaurants serving visitors to the palace need grease traps emptied too.
Our crews work in south-west London and north Surrey most days and we answer the phone 24 hours a day, 365 days a year.

What we do for Hampton Court customers
Flood water removal
When high river levels flood a basement, garden or chamber, our tankers pump the water out and take it away. Once it’s gone, we check the pumps and drains.

Drain clearance
We clear blocked drains in homes and businesses with high-pressure jetting and tell you what caused them.

CCTV surveys
A CCTV survey shows the condition of drains under period and riverside homes, with a written report and photos.

Drainage around Hampton Court: what to know
Three rivers meet here.
Riverside pumps
Pumps are essential for many riverside homes. Service them before winter, when river levels rise.
Non-return valves
A valve on the drain stops river water backing up into your home at high levels.
Visitors
Pubs and cafés near the palace get busy, so grease traps fill faster in summer.
