Why Impact Moling?
Impact Moling is a cost effective and environmentally friendly solution for many underground installation projects. Instead of digging trenches to lay pipes/ducts and cables Flow External Plumbing use a technique called Moling, which, uses a smaller footprint with no need for deep excavations and operates through various ground types, but not all.

Water Pipe Repairs & Replacements

Our water mains replacement starts from the stop tap at the boundary of your property up to the connection inside your house, giving you a single, seamless water supply replacement that has superior integrity and flexibility, leaving it less prone to splits and cracks with none of the risks of lead contamination.

External Moling & Trenchless Installations

Impact Moling is a technique in which a pneumatic piercing tool is used to create a bore hole. The ground is compacted and displaced rather than excavated and removed, therefore disruption and reinstatement are minimal.
Impact Moling is the simplest and least expensive trenchless technology installation method.

With washing machines, power showers and central heating systems needing water, old supplies (often Lead) do not provide an adequate flow due to a smaller bore size. This poor pressure can be increased through the installation of a greater internal diameter pipe of 25mm or greater to your property, resulting in increased pressure from your taps.

Client Testimonials

Barnet EN4

Dear Karl, May we take this opportunity to thank you for an excellent job, as you are aware the reason for the initial call was the stream of water pouring down our front driveway due to a broken stop-cock. After an initial phone call, you arrived the next day (at the agreed time) to assess the work. You explained that whilst replacing the broken stop-cock the fitting of a new water main to replace the original lead water main would be beneficial. You advised us of the cost at the time, which we thought was very reasonable and you said that you would phone us the following day to advise us when you were able to undertake the work. Within a week of the initial phone call the work was completed to a very high standard. Neighbours who saw the depth of the hole that you had to dig to get to the water main have commented that “you wouldn’t have known your drive had been dug up” as the block pavers were replaced to their original state (if not better)!

As we have a pressurised water system the increase in waster pressure due to the new water main is incredible.

For these reasons, we would definitely recommend ‘Flow External Plumbing’ to anyone that requires your services.

Mr & Mrs P James

Winchmore Hill N21

I am writing to thank you for completing the excellent job carried out on Thursday in replacing the lead service pipe. I was delighted that you were able to install the new inlet pipe by using the moling technology, thus avoiding excavating more of my driveway than the original inspection hole. I appreciate the time and extra trouble you and your colleague took in ensuring there was no damage inside my home as you connected the internal services.

Please use this letter as an introduction to other client sand rest assured that if i here of family or friends facing similar problems with deteriorating lead pipes i will recommend your firm.

Mr M Griffin

I needed to have the old lead water main replaced with a new plastic pipe at my property. A neighbour introduced me to flow. I found them to be incredibly efficient, from arriving on time to give us a quote.

On the day the work was to be carried out, they arrived promptly with a courtesy call to notify me of their arrival time. The work was carried out with the utmost efficiency. the finished job was of an excellent standard, and i was left with no mess at all. i would recommend this company to anyone considering any external plumbing.
