I have recently had my property connected to the main sewer
The contractor piced up all the existing house connections and ran a 110mm plastic drain to the sewer in the road. Access points were installed at every connection and change of direction, but no manhole/access poit was installed at the property boundary prior to connecting to the sewer. The total distance from the last access point to the sewer is approx 22m. I now find that some three weeks after completing the work that all access/manholes are full which tends to suggest that the final run is blocked. Can you advice me if there should be a access/manhole at the boundary, prior to the sewer

the first thing to look is see if they removed any bung in the conection in the road,if its a vacume system has the pot been powered on? why 150mm in a house connection?,second did building control check the fall and to a water test on it? if not why not then get the contractor back to fix it unless it is blocked with something call a jetting company out then go from there, you need a manhole max distance 40m its advisable to have one at end of property but again building control will advise on that depending if you connect into a manhole in road if so there is little point,if going into a junction a manhole is needed

I am pretty sure if its a new sewer connection you have to have a manhole within 15mtrs of it, manholes on the boundary are always a good idea but sadly not enforced by building control.

Thanks , My mistake, the pipe size is 110mm.
The installation was checked and passed by the local building control officer, so I am assuming that all the necessary tests, and inspections were carried out
I'll get a drain company in as you suggest, in the hope that they can clear the problem. but was wondering whether I should have a manhole at the boundary, as it would make rodding easier in the event of any future problems

as i said depends if there is manhole in road close to property,last m/h 22m away one at boundry would be nice but how deep are you at that point? a plastic m/h could be put in but if you have to goto precast concrete rings you can soon spend 500quid, what part of country are you

Suggest you get the contractor back.
Were they allowed to connect to the main sewer run themselves??

I dont know how deep it is at the boundary, will have to check with the contractor, butI think I'll get the drain cleaners in first, then discuss with the BCO, and contractor on the merrits,and cost of fitting an extra manhole at the boundary

did he actually connect to a manhole, or put in a new manhole in the road?
i am hoping he did'nt just use a saddle ???
have you looked in the existing manhole to make sure its isnt bunged? also have you tried rodding it?

I wouldn't get anybody but the original contractor involved at this stage - unless he can prove it is blocked with an item of your making, the problem rests with him, in my opinion. How long has this connection been in place?
Rodding it would be the first thing you could do at low or no cost, that would give you then an idea of where the obstruction might lie.
Surely the type of connection would have been approved/inspected by the relevant utility operator and the seal of approval given? That is what happens when we do one.

I would like to thank everyone for your advice. I couldnt rod it as the length of run from the last access manhole to the sewer is greater than the length of my rods. A drainage company arrived this morning , and freed the blockage with his pressure hose. I have also arranged to meet the contractor who installed the drain,and BCO, in order to discus the possible need for installing an extra manhole nearer to the boundary
Once again, thanks for all your advice
