According to drainage experts at Plumbers 365, across Reading, from homes in Whitley to businesses on Broad Street, the culprits are nearly always the same- non-flushable wipes ("ragging"), FOG (Fats, Oils, and Grease), and limescale build-up caused by Reading’s hard water. As often advised by drainage experts at Plumbers 365 nothing apart from the 3 Ps(poop, pee & toilet paper). Plumbers 365 drainage experts have identified the main offenders of blocked drains in Reading homes and businesses as: 

• FOG: Fats, Oils, and Grease from cooking that solidify into hard blockages.
• Wet Wipes: Even "flushable" wipes don't break down and cause huge blockages.
• Sanitary Products: Nappies, tampons, and pads should never be flushed.
• Food Scraps: Especially from waste disposal units.

Drainage experts at Plumbers 365 consider this a common and classic Reading problem where the answer is often a combination of both. Reading has a naturally high water table due to the rivers. If your cellar has standing water, it usually indicates a failure in the external drainage (French drains) or "hydrostatic pressure" forcing water through the brickwork as often observed by drainage experts at Plumbers 365. However, a functioning drainage system (like a French drain or land drains) is designed to alleviate this. If those drains are blocked or collapsed, they can no longer channel water away, making the damp problem significantly worse. A professional CCTV drainage survey is the only way to determine if a drainage failure is contributing to your damp cellar according to drainage experts at Plumbers 365.

Unfortunately, yes. Drainage experts at Plumbers 365 have often observed that many older parts of Reading, including areas of Caversham, have "combined" sewer systems where rainwater and wastewater share the same pipe. During intense downpours, the sheer volume of rainwater can overwhelm the system. Heavy storms can cause "hydraulic overload," forcing the mix of rainwater and sewage back up through your manholes. If the main sewer is full, the water has nowhere to go and can back up through the lowest point, which is often a manhole in a garden, causing foul water to spill out. Drainage specialists at Plumbers 365 can install a non-return valve on your drainage system to help prevent this from happening.

Drainage experts at Plumbers 365 advise food businesses in Reading that regular grease trap maintenance is non-negotiable to prevent blockages and comply with regulations. As a rule of thumb, we recommend a professional cleaning schedule of every 1 to 3 months. While the exact frequency depends on the size of the trap and the volume of trade, a busy town centre restaurant will need more frequent servicing than a small café. 

Plumbers 365 drainage experts note that Thames Water takes a strict stance on FOG (Fat, Oil, and Grease) pollution. If a restaurant is found to be blocking the public sewer with fat, they can face heavy fines and prosecution. Regular professional cleaning not only keeps you compliant but prevents the foul "rotten egg" smells that can drive customers away.

Plumbers 365 drainage experts often explain the difference between the two for clients asking them to imagine old tech vs. new tech where drain rodding uses manual steel rods to punch a hole through a blockage while high-pressure jetting uses water to scour the pipe clean. Drainage specialists at Plumbers 365 almost always recommend going for jetting in order to have a long-term solution. The major differences between rodding and jetting as outlined by drainage experts at Plumbers 365 are: 

• Drain Rodding: Involves pushing a series of connected rods into a drain to manually break up a blockage. It's effective for simple, nearby clogs but can't clean the pipe walls.
• High-Pressure Water Jetting: This is the professional's choice. A high-pressure hose is fed into the drain, firing powerful jets of water that blast away blockages, descale pipe walls, and flush out all debris. Plumbers 365 also offers high-pressure drain jetting for commercial clients.

According to drainage experts at Plumbers 365, knowing if a drainage problem is your responsibility or Thames Water’s is quite crucial. If the drain is inside your property boundary and serves only your home, it is your responsibility. If it is outside your boundary, or if it is a shared drain (serving you and a neighbour) inside your boundary, it usually belongs to Thames Water. 

Drainage experts at Plumbers 365 assert that since the transfer of private sewers in 2011, many homeowners don't realise that shared drains are no longer their headache. If you have a blockage in a shared manhole in your back garden, you can often call Thames Water to fix it for free. However, a drainage specialist like those at Plumbers 365 are often needed first to identify where the blockage is and prove who is liable. 

According to drainage experts at Plumbers 365, if you are building an extension, you must have a plan for your drainage approved by Reading Borough Council. Crucially, if you are building over or near a public sewer (which is very common), you will need a "Build Over Agreement" from Thames Water. Drainage specialists at Plumbers 365 urge that you must comply with Building Regulations Part H. 

Drainage experts at Plumbers 365 have often observed that the Reading Borough Council will not sign off on your extension without the “Build Over Agreement”. We assist homeowners by performing a pre-build CCTV survey to map the sewer's location and depth. We then provide the technical drawings required to prove your new foundation won't damage the public sewer infrastructure.

You need a specialist with portable electric equipment like those at Plumbers 365. Large jetting vans cannot reach the 4th floor of a town centre apartment block. Look for companies equipped with electro-mechanical coring machines (rotary snakes). Drainage experts at Plumbers 365 have often observed that in modern apartment blocks near Reading Station, blockages often occur in the stack pipe or kitchen waste lines. Since we cannot run a hose from a van parked on the street, we bring portable machines inside. These units are clean, quiet, and capable of clearing blockages through the toilet or sink trap without needing external manhole access.

Plumbers 365 expert drainage specialists advise against use of chemical drain cleaners on old clay pipes found in Reading since harsh chemical cleaners are corrosive and can attack the pipe joints, creating bigger leaks and problems over time. But that is not all, according to drainage specialists at Plumbers 365, chemical drain cleaners are often ineffective and just move the blockage further down the pipe, making it harder to clear professionally. Professional jetting is a far safer and more effective solution. 

Large parts of Reading are built on clay soil which is "reactive," meaning it shrinks in summer and swells in winter. This ground movement shifts underground pipes, causing joints to open up or rigid pipes to crack (shear). In areas like Tilehurst and Earley, drainage experts at Plumbers 365 frequently see "stepped joints" where one pipe section has dropped lower than the next due to soil movement. This creates a lip that catches debris and causes persistent blockages. During dry summers, the shrinking clay can also pull pipes apart, inviting tree roots to enter in search of moisture as often seen by drainage experts at Plumbers 365.
