I added the Dutch Water tech bio recap LQD to my 5000 L rainwater tank in February this year as there was a slight smell from the water. Two weeks ago, the water in the toilet smelt really bad. I wanted some advice on what to do next and phoned the company but got an answer phone. Left a message but they didn’t ring back. Ordered another bottle. Added that. Hope the smell goes.

Really struggled with septic tank and drain smells. This is the only product that works. We are so pleased. Thank you

I had a problem with a poor soakaway flow in my system. Three weeks later I thought this product may have helped. It didn't.

Easy to use Website/Account, and products turned up quickly and well packaged.

I have a 5000l rain water recovery tank (used for garden irrigation, toilets, washing machine and outside taps) that occasionally gets overrun by contaminated water from an ageing and easily blocked sewer operated in the UK by Southern Water. In the past I have spent several £100 on a contractor to empty and clean the tank. I'm not prepared or equipped to climb into the tank for a proper hands on clean up. This time I had Southern Water empty the tank as part of their clean-up. I then used a stick pump to clear more water and hosed the tank before stick pumping it again. After online research and a rapid email exchange with Dutch Water Tech I added 2500l of clean water and 0.5l of BIO-RECUP LQD. After a few days the water from the tank was clear and odourless. The cost was a fraction of commercially cleaning my tank. I am making a claim to Southern Water for the cost of the product and pump. Well done Dutch Water Tech!

Bought this as our outside drain is clogged. Easy to order and arrived quickly. Item instructions are easy to follow and it doesn’t have a bleach like smell. Item does seem to be taking effect and I will certainly look at purchasing from this site in the future.

Was most cost effective online and delivered as predicted.

Sadly the product I was suggested to buy did not work or manage the situation even though I called to get a recommendation.

Easy to use website with lots of helpful advice and very quick delivery. Will review the product once I've used it for a month or so!

Excellent service

Easy to order from the website. The package came quickly and was well packaged. Would both recommend and use this company again.

We had a problem with a poorly draining leach field and tried various things to sort it out to no avail. Then tried K570 Leach and Drain Field Opener after reading reviews. We put a bottle in every month for six months and gradually noticed an improvement. We now empty a bottle in every two months. It seems to be working.

Fast, friendly and very professional. Really good company to deal with. Recommended a certain product and it worked a treat in the septic tank.

I have purchased this product previously and no issues again this time.

Very good experience

Prompt delivery. Do not like using PayPal.

Very efficient service from seller. “Black water” worked really well, poured the whole bottle into empty narrowboat holding tank, filled the tank with clean water, waited one week then pumped out again. Lots and lots of “crud” came out and then totally clear on final rinse. Very very pleased with the outcome. Highly recommended.

I have always found the Septic Tank Shop to be very easy to deal with, whether that is for purchasing their goods or ringing up for technical advice, which they are always happy to give. I have no hesitation in recommending this company and will certainly use them again.

Very poor

Had problems with our tank draining, it had become really slow and was getting close to the top of the tank. I brought some tank & drain field cleaner. Put a total of three bottles in over the course of two months before noticing a difference. Now I put a bottle in the tank after having it emptied to replace the bacteria.

The products have improved the drainage from our soak away. The dispatch is very prompt and efficient. Would not hesitate to recommend.

I wanted a way to improve the efficiency of my septic tank. Septic Tank sent me their product, which was easy to use and seems to be doing the job.

After initially realising that the product we needed was out of stock I emailed the Septic Tank Shop asking when it’d be available and got an immediate response (saying it’d be a few days) then an email when it was in stock. We ordered, it was dispatched promptly and has made a big difference to the quality of our rainwater. We have had a rainwater harvester system for 10 years but this summer the water (which flushes our toilets) although not smelling, looked a little off colour and was frothy. After only a few days it has cleared significantly. We will definitely use this company and their product again.

Very easy transaction

Requested Products arrived in reasonable time. However products do not work or make any difference whatsoever.
