Extention over drain cover and digger

Internal manhole covers are available (these have a double seal lid) so you could keep the inspection chamber where it is. It is better (if possible) to re-route drains to outside the building as this avoids internal inspection chambers which have to be accessible.

A one tonne+ mini digger is 900mm wide. The 'Fred Flinstone' roof is removable for low height access. There are smaller diggers (0.8 tonne) but you may not be able to get the depths you require with one of these.

 

double sealed double cover will set u back about 200

 

Nonsense, we buy them for around £50

 

Look at this list, halfway down are the double seal recessed tray type, list price £57

move the drain

 

> move the drain

is that an order or a suggestion?

 

take your pick,

I for one would not want to be lifting a floor to rod a blocked drain, would you?

Watch out vcm, it might be his area

 

Moving a drain can cost thousands depending on the complication of the layout.

If I had a double seal manhole in my floor and the drain blocked, I would rod it from upstream and downstream of the blockage from outside first. When the blockage is cleared I would then remove the double seal lid to clean and inspect.

We're comparing a £50 manhole lid to a £00000000 drain move job. How often do good drains block?

Weigh up the costs and make a decision on that.

 

The tracks on my 1 ton digger narrow in so it will pass through an opening 800mm wide. With the canopy down it's about 5' high. It can dig down to about 6'.

 

My parents have an internal manhole it is tiled right over and you can hardly notice it.

To my knowledge it has never been lifted in the 20 years since it was installed....

 

Just done an extension with the same problem. BCO was happy to put in a dbl seal cover (to eliminate odours) and put in a new rodding eye outwith the extension so that any blockage can be sorted without needing direct access through the manhole.

 

i said double sealed, double lid, not just double sealed.

What do you mean by <u>double lid</u>, have you a trade link to a supplier as there are many ways of describing manhole fittings.

 

if you can rod the junction from outside, in each direction I would let you dispense with the MH and use a Y junction, ask your BCO, or are you doing it without approval like the rest of the nutters on here?
