Slow draining sinks

Mocrie14

All my sinks have started to drain very slowly over the past couple of months. Toilets and showers are fine. I have checked drains and septic tank outside and there is no sign of any blockage etc. Anyone know what might be causing this and what I can do to sort it?

Thanks

Sinks will most likely not be piped to your septic tank but piped to a soak pit. You will need to check this pipework/soak pit. You should still have rodding access.

I use washing soda crystals to see if it's an internal issue.

99c in your supermarket, loads of hot water, and it clears a lot of blockages.

Mind your hands though!

Run my dishwasher and washing machine empty with a load once a month to clear them out too!

Not sure I have a soak pit. I have a septic tank which then feeds up into a Bord Na Mona puraflo system. As far as I can know all water/waste coming out of the house goes into the septic tank and then the liquid is pumped up to the puraflo tank?

Im not supposed to use Mr Muscle etc as it destroys the bacteria in the puraflow tank. Not sure about washing soda crystals

Tried that already but no real improvement!

There could be a poor fall on your wastes and over the 6 months have build up with muck making it worse. Can you see where they exit the house (cleaning eye's ect) or are they all concealed.

Yep check the fall on the sinks. I saw this recently when I was adjusting a stack, the sink waste had no fall on it.

When I cut the sink pipe open it was 1/3 blocked, and it's only a 1.25 inch pipe to begin with.

There's a nice fall on it now, also opened it up onto 1.5 inch pipe...
