Hi
Couple of years ago I installed a land drain in my front garden and connected it in to a foul water manhole (brick built).
All I did was to knock out a couple of bricks and cement in my clay pipe I did this 3 rows of brick down from the top the manhole. Itâ€™s over 5 feat deep so no chance of it filling up without me clocking it! I have never had any problems. The new land drain dosent cover a very big area I have just seen how it should be done on your site wish I had looked before.

Will this ever be picked up on in a survey when I sell the house because if it will I need to sort it before I redo the drive?
What do I need to do dig to the bottom and put the pipe through the benching?

Thanks andy

There's a new "Housebuyers Pack" coming into force in the very near future and this is supposed to eliminate many of the loopholes and gaping chasms in the existing survey set up when it comes to buying and selling property.

As my area of interest isn't really in the survey side of the industry, I'm not sure if or how this new arrangement might impact on many of the 'features' that have been benignly overlooked by some surveyors in the past, keener to pocket their fee and get out of thee cold and wet than to undertake a thorough assessment of external pavings and drainage. However, the suggestion from some of those now being trained as "almost surveyors" is that the condition of the drains will be covered,a nd so there could well be a risk that your bodge would be spotted.

First of all, you should NOT have linked a land drain into a foul MH unless there was absolutely, definitely and verifiably no other alterantive. In such a case, the link should be at invert level, and should be trapped to prevent gases escaping.

When there's a significant level diff between the invert level and the incoming pipe, the usual solution is a backdrop, as shown here
