Blocked drains
"We recently noticed our downstairs WC was not flushing properly, and our outside man hole, was flooding and smelt terribly. I got in contact with happy drains and they hooked someone in within the next 2 days as I requested. The guy came to site, and told me exactly what he was doing and what he thought the issue may be. He fixed it in great time and was very informative. I hope I don't need to call happy drains again, but if we ever need someone to help us in the future, we will look no further. 10/10"

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.

Blocked kitchen sink drain
"I noticed that the patio was awash with soapy water and realised that the drain leading from the kitchen sink was blocked and overflowing. I phoned Happy Drains and they were so helpful. Arranged for someone to call round between 1 and 3. I arrived home at 12.55 to find them patiently waiting outside. They were very friendly and helpful. Did a thorough job clearing the drain, lifting the manhole cover and making sure the water was flowing freely. I was delighted with their service and would definitely recommend them."
