yes, more problems!! Keeps me busy :cry:

Its an old brick built septic tank, doesn't out flow to a watercourse/ditch so meets the regs. Theres 3 pipes going to this chamber but will have a look anyway, its a plastic chamber so probably not that old.

Hi, it doesn't block up, but I can see the standing water in the chamber but the chamber at the head of the septic tank is dry, I have rodded but its not blocked. I am thinking of digging out the other pipe run towards the house so I can lift the chamber up.

Hi We have a septic tank and the waste is not flowing properly and I've dug down to expose the waste pipe and found there is no fall to speak of. The waste pipe runs between a chamber and the tank and is almost level, in some areas even slighty uphill according to my spirit level. I've only...

Yeah it’s not ideal and may have to put a barrier around it.

@lo its flags over the whole lot, with two chambers - so sounds like the ones you have built previous. Yes it is old but doesn't output into a stream/ditch so compliant with 2020 regs (despite what I am being told by salesmen of waste water treatment plants)

The Y-piece connection to the straight piece is encased in concrete, so i will need to go easy, keep you posted!

I was looking to sort out flooding issue when it rains heavy at front of house, with maybe connecting an Aco-Tray to the existing drain then uncovered a few issues with the existing drains that I need to repair first (always the way). Some advice please.... As per the photo - can I keep the...

Ah okay, I could have saved some money with the AAV. The septic tank is an old style concrete thing with flags over the top, so well ventilated.

Hi, yes its more than 3m so I will drop into 110mm as it goes underground (this is all external grassed area) and go around to join up the stub-stack. For the open vent I was intending to install the stub-stack with an AAV (sited behind the toilet)

Hi I am looking to install a shower one side and the toilet the other, so I need to join the two wastes together. It is best to extend the 110mm to the outflow of the 40mm and join up there with a 40/110mm adaptor? Does it matter where the stub stack with AAV will be - assuming I just need...

Hi, yes it has been Tee’d off the cistern’s feed pipe, probably when the house was extended. I’m not too happy about the smaller diameter so for price of it may change that out for 28mm until final 10cm

I removed the shower yes. To confirm whether variable flow was due to the shower, but it isn’t. I’ve not checked pressure - I’ll do that, may need some form of adapter. I’m thinking if pressure is low then flow is going to be weak.

Ive took the shower unit out the equation and measured the flow going into to the shower unit I need to measure the pressure and compare with downstairs yes.

Hi I have an electric shower in the en-suite that takes it cold feed from a T off from the same pipe that feeds the 2 header tanks in the attic - so it must be the mains. From that is a smaller bore copper pipe of about 2.5m length to the shower. However the flow changes from 2 to 4 l/min. What...

thanks Hugh, yes good point - would also need to install a sink as well. I also read that by regulation sub stacks are not permitted outside but it is common practice that they are

Hi All, Struggling to find a plumber, so tackling this myself. This is a new install (single storey) so will need waste piping all way to the exiting septic tank. Would like to run a few things by you.. Would a 'stub stack' the way forward with this? With boss pipe for the x2 40mm wastes then...

Well today I'm plumbbob. Never mind Dan_Robinson..... He has BO.

Just an additional comment, See the thread for more info in how to resolve. In short the tap, or its innards need replacing. Not yet sure what the underlying reason for this is though.

Yes, that is happening to my hot water tap too. I have to turn if off then on again to get some flow before it dies away again - maybe washer perhaps?
