What We Install

Handy Ivan helps with common water filtration and drinking-water upgrade projects, including:
Under-Sink Water Filter Installation

Under-sink water filters are a practical way to improve access to filtered drinking water without taking on a large project. Handy Ivan installs many customer-supplied under-sink filtration systems when the cabinet space, sink setup, shut-off valves, faucet location, and project scope are appropriate.

Before scheduling, please provide photos of the under-sink cabinet, existing faucet area, shut-off valves, sink deck, product box, and model information. Clear photos help determine whether the project may be a good fit for a virtual estimate.

Reverse Osmosis System Installation

Reverse osmosis systems can provide dedicated filtered drinking water for kitchens, break rooms, rental properties, and small commercial spaces. Handy Ivan installs customer-supplied RO systems when the existing plumbing, drain connection, cabinet space, and product requirements are appropriate.

Some reverse osmosis systems may require drilling, additional clearance, special connections, drain adapters, or installation steps that depend on the sink, countertop, cabinet, and existing plumbing conditions.

Filter Replacement & Small Filtration Updates

Existing filtration systems sometimes need filter cartridges, housings, tubing, or small components replaced. Handy Ivan can help with practical filter replacement support and small filtration updates when the system is accessible and the product details are available.

For best results, provide the system brand, model number, filter part number, product link, and photos of the installed system before requesting service.

Countertop Hole Drilling for Filtered Water Faucets
Handy Ivan can drill a countertop opening for a customer-supplied filtered water, reverse osmosis, or drinking water faucet when the countertop material and project scope are appropriate. This may include select quartz, granite, marble, solid-surface, laminate, or similar countertops, depending on access, thickness, location, product requirements, and risk of cracking or damage.
