Rats, mice, rodent and vermin drain problems
Rats will use drains just like ‘Londoners use the Tube’ simply to travel from A to B to feed and nest and they love damaged or redundant drainage systems which can allow vermin to enter properties.
If you have a rodent/vermin infestation that your rodent/vermin contractor cannot control, this may be because of a drainage issue. We will find the defects and access points the rat may be using. We will offer you an appropriate solution be it drain repair or the installation of a WRc tested and certified 'Anti Vermin / Non-Return Valve'.
What do our Anti Vermin/Non-Return Drain Valves do?
- Stops rats and other vermin from entering homes. In effect by fitting a stainless-steel flap, that acts as a one way swinging door allowing waste out but nothing back in.
- The rubber seal prevents noxious fumes and smells from entering properties.
- The flap has an inbuilt stainless steel plate to stop rodents biting through, providing efficient pest control.
- The valve is completely re-usable during any drain cleaning and drain maintenance purposes fully removal and re-usable.
- Stops backflow of effluent from a blocked main sewer flooding into your property back through the drainage system.
- The clever design means the flow of waste is increased when passing through the valve; reducing blockages.
Building an extension?
- need a CCTV Drain Survey?
If you are doing building work over the top of or within 3 metres of a ‘Thames Water’ public sewer or drain you must ensure that no damage or restrictions are made to the ‘Thames Water’ drainage assets.
So, if Thames Water have asked you for a ‘build over’ survey because you are ‘building over or close to a public sewer’ our CCTV survey will provide all the answers and information you need.

Kitchen Sink Drain Blockage
"Telephoned Happy Drains early morning. Was told a technician would come to me late afternoon. He arrived at 4pm after telephoning to advise his arrival time. He asked where the blockage was and then got on with clearing it. No time wasted. Once the U bend had been taken apart the blockage was sucked out. Then the U bend was reassembled to show me the blockage had been cleared. All done very efficiently and effectively with very little mess being caused. I was very pleased and impressed."

(you know what comes next) deep breath intake, etc..). Damian was a pro and worked his way round the problem until it got done. I'm not squeamish for these kind of jobs but I soon realised that blocked drains require professional equipment and experience! Happy customer"

1st time customer - Excellent experience
"1st time using Checkatrade. Polite and efficient experience from beginning to end, with clear/ transparent pricing + quick availability of plumber. I chose to use Happy Drains... who were available same day to unblock kitchen sink. Damian from Happy Drains was friendly and cheerful, but always polite and professional and persistent with unblocking drain. Damian had a powerful acqua vac that was required to unblock the drain. Not an easy job, but Damian persisted and determined to get job done. No surprises with charges...exactly as quoted and very reasonable. Recommended."
Blocked external drain
"I had a blocked drain (external to the property). I previously had someone to look at and they explained that the drain had likely collapsed and quoted to fix (over £1k). I thought I would double check. Happy Drains visited and drain was clear within minutes (blocked trap) with no requirement to dig up garden and replace drains (or use a camera). 60 day guarantee inc in case it blocks again. Engineer was polite, friendly, cleanly dressed and professional. As he said 25 years of experience. Great job, highly recommend (and I will be recommending further)."
Back garden drain unblocked
"The challenge was to unblock my drain in the back garden with no rear access. All equipment needed to be brought through the house. It was too much of a risk to use a pressure washer for a single crew. However the engineer fully cleared the drain using his available tools/ equipment."
Blocked drain just before Christmas
"Very friendly service, appointment obtained quickly and resolved our problem simply and effectively. Would definitely use again. "
