Guests blocked the drains by washing their clothes in the bathroom

[Chris232]

I recently had 2 guests for an overnight stay.

After they had left I found the wetroom floor drain blocked as well as the Basin trap blocked by dirt and stones.

They were cycling the South Downs way and had got extremely muddy.

As winter approaches I will be welcoming more guests whom are walking the route

I need to make a sign

"Previous guests blocked the shower drain and basin by washing their clothes in the bathroom
Plumbers Cost = £280
Outside tap and bucket is available for your use"

But the wording does not seem right, any suggestions ?

@Chris232  How about "If you need to rinse out or wash muddy or sandy clothes, please do a pre-rinse in the bucket and outside tap first so as not to clog up the drains and incur a charge to call a plumber (this has happened with previous guests). Thank you for your attention to this."

Thanks @Sarah977  I need something short and punchy to print and hang in the wet-room.

May use yours to put in the House manual

"Kindly refrain from washing outdoor gear/clothing in the shower or sink basin 
Plumbers Cost for blocked drains = £280
Outside tap and bucket is available for your use"

Excellent, Thank you.

Short n sweet. Perfect.

Yet another sign to go up in the bathroom.
