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.

A few more excellent reviews to reassure you...

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."
Drain unblocking
"Having used Happy Drains services a few years ago at a previous property, I called them again to sort out a blocked drain at my new home. The plumber came out the next day and resolved the issue quickly. He explained everything throughout the process and was very thorough. Their service is very reliable and reasonably priced and I wouldn't hesitate to recommend them. "
Bathroom sink unblocked
"I attempted to unblock our bathroom sink using a plunger, then sink clearing chemicals and finally removing and confirming the u-bend was clear, all to no avail. I went on the Checkatrade website and found Happy Drains. I called and booked a plumber to come the following day. The plumber arrived as expected, was professional, polite and got to work straight away. He cleared the blockage that was further down the pipework using a wet vacuum within 10 minutes. It's been perfect ever since."
Blocked outside drain
"very efficient service. Fixed price quoted over the phone and invoice received by email. As promised, I received a call to tell me he was on his way. Once he arrived he got on with the job, with the minimum fuss, cleared the drain, thoroughly tested to make sure it was completely clear and left with no mess."
Main drain for household waste water blocked
"Engineer arrived in good time. Could see what the problem was and removed the blockage effectively. He cleaned the area afterwards. I would be very happy to use this company again and recommend to others."
Kitchen external drain blocked, and now it's now.

Unblock an outside pipe

Drain unblock
"Tommy was prompt, polite and resolved the issue. He called me the day before and confirmed the exact time he would arrive. Job completed with minimum fuss. Very happy with the service."
Sewage drain unblocked
"Cannot recommend enough. Called and had appointment for the next morning. Jason called to confirm he was 20 minutes away, arrived promptly and the issue was solved within 20 minutes! He explained clearly what the issues were. Excellent service from start to finish. Highly recommend đ?'?"
Unblock drain re kitchen sink
"Happy Drains sent Alex who was superbly focused and dedicated. He rapidly identified the blocked kitchen sink that had not been resolved by a plumber was a drainage issue (as suspected), found the drains, identified the correct one linked to the kitchen, sent a camera down to find the blockage, and rinsed it away with high pressure water jet. Took an hour, with a lot accomplished. No additional or unexpected charges. Very happy with their service and professionalism (given dealing with these sorts of issues can be a minefield of distrust)."
