Queen Elizabeth II’s supplier of fruit preserves has found itself in a royal jam – amid a drop in water pressure in a neighboring estate, according to reports.

Wilkin & Sons, a manufacturer of preserves and marmalades in Triptree, Essex, is accused of causing the water woes at the Nine Acres estate, where residents say they can’t shower, wash dishes — or even flush their toilets, the Telegraph reported.

Resident Charlie Garnish, 27, first reported the problem last month.

“There was not enough pressure to run a shower and I was having to keep water supplies in the fridge for drinking,” he told the newspaper.

“We even had to have buckets next to the toilet, it was ridiculous. I’ve put in an official complaint to Anglian Water and have been in constant discussions with them,” he added.

It is believed that the problems arose when the factory refills its huge water tanks that are used for irrigation of fruits grown at the site.

A spokesman for Anglian Water, which supplies the new estate, said a meeting with Wilkin & Sons is expected to take place next week to address the problems.

“In the meantime, we’ve agreed with the factory that we will advise them on the best time of day to refill their water tanks, so that it has minimal disruption for nearby residents,” the rep said.

Another neighbor, Gavin Smith, 42, said: “We’ve only been here for six weeks and it’s lovely so it was a shame that about the water.”

Chris Newham, a director at Wilkin & Sons, said the company has been frustrated by the matter “as we know all our new neighbors.”

“Having worked with Anglian Water for over a year to ensure the correct supply was available to our site, we have had to revert to our old supply until such time as the pressure issues with the new supply have been resolved to everyone’s satisfaction,” he said.

A mother-of-two who lives on the estate said the water pressure “quite often drops to near on nothing, to the point where the boiler can’t even work because there is not enough flow through it to start.”

“Having children, it makes it impossible to bath them or wash up or do mundane things, just the every day stuff. It is a bit of a pain in the bum,” she told the BBC.

In 2010, the Queen visited Wilkin & Sons, which has been a Royal Warrant holder since 1911.
