A swimming-pool plant room was seen and the pumps were not run. What water-tightness of the pool has the home survey not tested?
The home survey has not tested the water-tightness of the pool. The plant room was seen and the pumps were not run, so nobody circulated the water, loaded the pipes or watched the shell under working pressure. Seeing filters, pumps and valves is a visual note of equipment at rest. It is not a leak test of the tank, the liner or the buried pipework. The survey has recorded the plant it could see. It has not decided that the pool holds water, and it has not decided that it leaks.

What is the fuller explanation?
Pool plant is outside the ordinary run of a home inspection, and a Level 1 style of look is visual. Pumps that stay off tell you they were not operated. They do not tell you the shell is tight. A waterline stain, a damp plant-room floor or a soft path beside the pool would be separate observations, if they were there. None of those, and none of a dry floor, replaces running the system.
If water-tightness matters to the purchase, ask a pool specialist to test the shell and the plant, and keep that report apart from the home survey. Tell your solicitor the inspection saw the plant room and did not run the pumps. Do not describe the pool as tested when you speak to an insurer or a lender. The home survey's limit is the point. It is not a certificate that the water stays in the pool.
What should you ask your surveyor?
- Which parts of the plant room did you see while the pumps stayed off?
- Did you make any observation of the shell, or only of the plant at rest?
- Are you recording that water-tightness was not tested?
What are the typical next steps?
- Treat the pool's water-tightness as untested.
- Read the plant-room note as equipment seen, not pumps run.
- Ask a pool specialist if the shell and pipework must actually be tested.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
If the pool is full, has the survey proved it does not leak?
No. A full pool shows that water was in it at the visit. It does not show that the shell holds, or that the pipes hold once the pumps run. The survey did not run the pumps and did not test water-tightness.
Does a tidy plant room mean the liner was inspected?
No. Tidy equipment is a view of the room. The liner, the shell and the buried pipes are a different inspection, and this one did not run the pumps. Water-tightness remains untested whatever the floor looks like. A swept floor does not stand in for pumps that stayed switched off.
