Perhaps everyone else already knows this but thought I would post a warning just in case... Despite the Noddy Wipes my son loves saying they are "flushable" in 5 separate places on the packaging that apparently does not apply to anyone who has a drainage systems that is not brand new.
We've been using them since we started potty training in Nov last year, and yesterday morning as OH was in the shower I noticed the water bubbling up in the garden. I went out for a look - the whole system was backed up - raw sewage and all! Gross. Thankfully DynoRod were stars and had it all fixed within 4 hours, but as soon as the engineer saw my little boy he asked if we flushed wipes. I showed him the Noddy Wipes and he immediately said yep, that's your problem, seen it a hundred times, they say they are flushable but in older systems they build up and block them.
So after handing over a cheque for £156 
I sent an email straight off to the Noddy Wipe manufacturers (cc'd to Watchdog)asking for them to reimburse me.
I hope by posting here I will save some more people a wasted, gross and expensive Saturday. Or maybe everyone but me knew this?!?
