Product description

Our 110mm water and rodent non return valve guards against pests such as rats entering properties through the sewage system, and protect against the backflow of water and sewage into your property in times of flooding.

First Class Service

Celia Howat (Verified purchase)

My experience with Automated Enviromental Systems has been over a couple of years. The quality of service and products purchased excellent. Whether I seek advice on heat pumps, water pumps, salt, alkaline issues, general pool health this company delivers. I am not technical minded and I have purchased several products from this company after they have discussed what I need... one pool heater to be returned without issue. I cannot thank Simon and various team members on the service, in particular follow up calls. This company comes highly recommended.

Simon understood our requirements- designed the solution - completed the order swiftly- engineers on site within the week- job completed without any issue- what appeared difficult they resolved efficiently and could not have been more helpful in completing to our full satisfaction.

Excellent company to deal with

Gail Roberts (organic review)

From beginning to end AES made this easy and kept me informed through out the process. The team that came to clean the drainage chamber did a brilliant job considering the scale of the work required. Excellent company to deal with, great communication and reasonably priced. This will now be my go to company for any drainage requirements I may have.

Good, old fashioned customer service

Terence (verified purchase)

Good, old-fashioned customer service. You get to speak to a human who is knowledgeable, listens, understands and advises expertly. The kit I bought was exactly what I needed, and recommended by AES.

Every time we ask for help these guys are just brilliant. This time I sent in a photo of a broken part as I had no idea what it was called. Incredibly helpful. Thank you!
