A dripping or low-pressure kitchen sprayer is one of those small annoyances that quietly adds up — wasted water, soap-streaked dishes, and frustrated guests in your holiday rental. The good news is that replacing a side-mount sprayer is a straightforward DIY job that needs no special plumbing skills. The video above walks through the process visually, and the steps below give you everything you need to do it confidently in your home, rental apartment, or hotel kitchenette in Greece.
When a Sprayer Needs Replacing, Not Just Cleaning
Before pulling out your tools, it is worth confirming that the sprayer itself is the culprit. Mineral scale from hard Greek tap water can clog the nozzle and a 30-minute soak in white vinegar will often restore a weak stream at no cost. But if the hose is kinked, cracked, or the coupling underneath the sink drips even when the sprayer is not in use, replacement is the right call.
Sprayer assemblies are inexpensive — typically under 20 euros at a Greek hardware store (sideremporio) or online — and the whole job, from shutting off the water to testing the new unit, rarely takes more than 45 minutes.
What You Will Need
Gather your supplies before you get under the sink: a new sprayer and hose assembly sized for your deck hole (usually 35 mm), an adjustable wrench or basin wrench, plumber's tape (teflon tape), a small bucket or towel to catch residual water, and a torch or head lamp. In older Greek kitchens the coupling nut under the sink may be corroded, so have a penetrating lubricant such as WD-40 on hand.
Check that your new sprayer hose is long enough to reach comfortably from the faucet body to the spray head with the head fully extended. Most replacement kits include a universal coupling that fits standard Greek and European faucet bodies.
How to Replace Your Kitchen Sink Sprayer
- 1
Shut Off the Water and Clear the Cabinet
Turn off the hot and cold supply valves under the sink — rotate them clockwise until they stop. Open the sprayer to release pressure and let any residual water drain into your bucket. Remove everything stored under the sink so you have room to work comfortably. A damp cabinet floor can make small parts hard to handle, so lay down an old towel.
- 2
Disconnect the Old Sprayer Hose
Trace the sprayer hose from the spray head down through the deck hole to where it connects to the faucet body or a dedicated coupling on the supply line. Use your adjustable wrench to loosen the coupling nut — turn it counter-clockwise. If it is corroded, apply penetrating lubricant, wait five minutes, and try again. Once loose, pull the hose free and let any remaining water drain into your bucket.

Remove the Old Hose from the Deck Hole
Unscrew or unclip the guide ring or collar that holds the hose in the deck hole (some models are friction-fit only). Gently pull the old hose and spray head up through the hole from above the sink. If the hole has a chrome sleeve or collar, inspect it for corrosion — this is a good moment to replace it if it looks worn, since the new kit usually includes one.

Route the New Hose and Connect It
Feed the new sprayer hose down through the deck hole from above. Below the sink, wrap two layers of plumber's tape clockwise around the male threads of the coupling before threading it onto the faucet body connection point. Hand-tighten first, then snug it up with your wrench — a quarter to half turn past hand-tight is enough. Do not over-torque; you only need a watertight seal, not a permanent bond.
- 5
Test for Leaks and Check Flow
Slowly reopen both supply valves. Watch the coupling under the sink for any drips — even a slow seep means the connection needs another half-turn or fresh plumber's tape. Once the connection is dry, press the sprayer trigger and check that the flow is strong and even. Run the sprayer for 30 seconds and inspect the hose along its full length for kinks or weeping seams before putting everything back in the cabinet.

FAQ
- Can I replace just the spray head and keep the existing hose?
- Yes, if the hose is in good condition and is not kinked or cracked. Most spray heads have a standard quick-connect fitting and simply click or screw onto the hose end. Hold the hose steady, depress any locking tab, and pull the old head off, then push the new one on until it clicks. This takes under five minutes and costs very little.
- My deck hole is larger than the new sprayer collar — what should I do?
- Most replacement kits come with a chrome escutcheon plate that sits flat on the sink deck and covers gaps around the hole. If the plate supplied is still too small, hardware stores sell universal sink hole covers in standard sizes (typically 52 mm or 65 mm outer diameter) that will bridge the gap neatly.
- The coupling under the sink keeps dripping even after I tightened it. What am I missing?
- First confirm the plumber's tape is applied in the right direction — wrap it clockwise looking toward the end of the threads, so tightening the nut does not unwind the tape. If the threads themselves look damaged or corroded, the coupling may need to be replaced rather than just re-taped. A replacement coupling costs only a few euros and threads onto the faucet body the same way as the original.
