Inspection chambers, longstanding issues

[havingdrainissues]

Hi

I have lived in my house for many years, unfortunately its been the norm to have to continually open 3 chambers to proactively flush them out. If we forget to do so then I simply have a nastier, bigger smellier job each time - say no more.

So I know what the issue is, I just haven't actually got anyone to fix it properly - nor there seems to be any definitive answer hence me posting here to get wider expert opinions.

So for two of my inspection chambers (these are all 4 inlet ones, obviously the issue is the 2 unused ones, wth no flow) these are connected to toilets that are 1 or 2 floors above (1 has one toilet - hits it at 90 degrees, the other 2 toilets and bath waste, one toilet hits it at 45 degrees and the other 90). When the toilet paper and waste lands in the chamber it splashes across to the other side and sits there - the unused ones are not blocked off in any way. For the one chamber that is highest up (fully accessible) it also hits the top of the manhole cover too, lovely!

The other one is near where they meet with the main drain. The flow from the toilets meets it at 90 degrees and again we experience the same build up of paper over time.

I have searched and searched and I can't really find a "product" that adequately helps - which would effectively mean that the chamber routes through without splashing into the unused chambers. I've heard people block up unused ones with cement or expanding foam etc.

Note 2 of the chambers are actually a metre down, only one of them is at a "workable" height (of one riser).

Thanks - just trying to work out if I've missed something obvious and get clarity on the best way forward to fix this properly.

Sorry - not sure how this got missed originally.

As with so many drainage issues, you really need onsite advice from a drainage professional to determine what would work best. If you ask at your local civils merchant (preferable to a builders merchant) they will be able to tell you who, locally, is a bit handy with residential drainage problems, and then you would be well-advised to ask this person/company to visit your home in return for a fee to take alook and suggest what might be rerquired, with no commitment from yourself that you would either follow their advice or give them the work....it's just advice and opinion that you require at this stage.
