Residents in Treorchy are returning to their homes after flash floods hit the area overnight.
A local pumping station failed during heavy rainfall causing 30 homes to be evacuated.
One resident told ITV News they saw water coming in through the front and back of their house.

Dwr Cymru has apologised after failure at a local pumping station combined with heavy rainfall caused flash floods in the Rhondda.
A Welsh Water spokesperson said:
Rhondda AM Leighton Andrews says he has visited some of the homes affected by last night's floods.
"Residents are understandably angry – this is not the first time there has been flooding and I have been to talk to them before about these problems. They are now looking to Welsh Water to make good on their promises.
"Welsh Water tell me that they accept that this is their responsibility to compensate residents. They admit that the pumping station failed last night. They say that they will have people on site today to talk to all residents affected."
South Wales Fire and Rescue Service say they received 'multiple calls' of flooding in Treorchy whilst on strike last night.
Up to 30 homes were evacuated in the Rhondda Cynon Taf area and a rescue centre was set up to help residents.
Members of the Fire Brigades Union across England and Wales staged their sixth walk-out since September in a row over pensions.
The strike happened between 6pm and 10pm.
Assistant Chief Fire Officer Rod Hammerton said he was pleased with how South Wales Fire and Rescue Service had managed its services during the strike action.
“As expected, the number of Firefighters from South Wales Fire and Rescue Service who chose to strike was high, which resulted in a large reduction in the resources that we had at our disposal.
"As such, we were unable to provide the same high level of response to incidents as we normally would and as a consequence prioritised our response to those in most critical need."
Rod Hammerton also added that contingency plans were put in place in collaboration with South Wales Police and the ambulance service to "ensure that the necessary advice was available to ensure that the resources that the public needed were available as quickly as possible."
It is unclear whether there will be further action by firefighters.
